feat(inventory): list-based ChangeInventoryPage + mobile-first UX + return ledger controls

- All ChangeInventoryPage sections (withdrawal/damage/waste/loss/transfer/
  stock-count/project-transfer) become list-based like the withdrawal
  section: pick a warehouse, see its stock rows, material name is only an
  optional filter; manual material/brand/unit entry removed everywhere
  except PURCHASE.
- RETURN redesigned: day-range presets (today/yesterday/7d/30d + Jalali
  custom range) with server-side filters, immutable-ledger returnable
  remainder per withdrawal (REF:[tx-id] note tag + FIFO attribution for
  legacy returns, round4 float-safe), destination warehouse selector.
- PROJECT_TRANSFER: row-based list with one destination project per batch;
  sequential submits keep failed rows inline with errors and drop
  succeeded rows; history dashboard untouched.
- PURCHASE: unit locked to catalog (search-only Combobox), wizard-style
  '+ register new material' option with yellow warning, optional Key-Value
  specs editor (replaces mandatory text chips), continuous-entry UX
  (warehouse/date kept, auto-focus, session log, duplicate warning).
- Mobile-first: responsive table/cards core (StockTable), numeric keyboards
  (inputMode+pattern), sticky bottom submit bar with dynamic counter above
  MobileTabBar incl. safe-area inset, horizontally scrollable touch chips.
- Backend fix (prereq of RETURN): GET /inventory/transactions date filters
  crashed with 500 under asyncpg (string vs timestamptz); parse to aware
  UTC datetimes (DB runs Etc/UTC).
- docs/inventory-ledger-gaps.md: ledger gap report (server-side return cap,
  standalone TRANSFER_IN, transfer row fallback, audit coverage, legacy
  REF backfill, UTC day semantics, pagination gaps).

-* **Traefik v3** is the public edge (ports 80/443); the frontend nginx only

-* Invoice upload requires an `accepted`/`arrived` quote; proforma has no restriction.
-* The supplier detail page (`/suppliers/:id`) shows the purchase history with
-invoice/proforma download links from MinIO.
-* **Material-Supplier Lookup**: Clicking a material in the catalog (e.g., on the `/units` page) dynamically fetches its assigned suppliers (`GET /api/materials/{id}/suppliers`). The backend uses an atomic JOIN to guarantee accurate supplier data (avoiding SQLAlchemy identity-map mismatches), and the UI displays a clean empty state («تامین‌کننده‌ای برای این متریال ثبت نشده است») if none exist.

-* If the frontend shows «اتصال به سرور برقرار نشد» → the api container is not

+# گزارش گپ‌های دفتر موجودی (Inventory Ledger Gaps)
+
+بررسی کامل منطق تراکنش‌های انبار (بک‌اند + فرانت‌اند) در جریان بازطراحی صفحه «تغییر موجودی».
+**این گزارش فقط فهرست گپ‌هاست برای تصمیم‌گیری معماری — به‌جز مورد ۱، هیچ‌کدام در این نسخه اصلاح نشده‌اند.**
+
+وضعیت‌ها: 🔴 ریسک بالای داده · 🟡 ریسک متوسط · 🔵 بهبود
+
+---
+
+## ۱. ✅ اصلاح‌شده در همین نسخه (پیش‌نیاز فیچر برگشت)
+
+**`GET /inventory/transactions?date_from=&date_to=` → HTTP 500**
+(`backend/app/routers/inventory.py` — list_transactions)
+
+ستون `transaction_date` (timestamptz) با رشته‌ی خام مقایسه می‌شد. درایور asyncpg تایپ سخت‌گیرانه دارد و این مقایسه با خطای `operator does not exist: timestamp with time zone >= character varying` کرش می‌کرد. هیچ‌جای UI قدیمی این فیلترها را صدا نمی‌زد، برای همین مخفی مانده بود.
+
+**اصلاح:** پارامترهای `YYYY-MM-DD` به datetime آگاه از UTC تبدیل می‌شوند (`YYYY-MM-DD 00:00 UTC` تا `+1 روز`) — همان معناشناسی کستِ قدیمی رشته در PostgreSQL با `timezone = Etc/UTC`. ⚠️ نکته‌ی مرتبط: مورد ۱۲.
+
+---
+
+## ۲. 🔴 سقف برگشت و اتصال REF فقط در فرانت است
+
+بک‌اند `RETURN` را دقیقاً مثل `PURCHASE` (افزایش ساده) می‌پذیرد (`inventory_service.py:268-299`) — نه به برداشت خاصی وصل است و نه سقفی دارد. با فراخوانی مستقیم API می‌توان موجودی یک انبار را بی‌نهایت تورم داد.
+
+UI جدید این را کنترل می‌کند (تگ `[REF:<tx-id>]` در note + محاسبه‌ی مانده + سقف ورودی)، اما **خود دفتر از سمت سرور محافظت نمی‌شود.**
+
+**پیشنهاد برای تصمیم‌گیری:** اعتبارسنجی سمت سرور — برگشت حتماً `ref_transaction_id` بگیرد و سرویس مانده را با قفل ردیف چک کند؛ یا جدول attribution جداگانه.
+
+## ۳. 🔴 TRANSFER_IN مستقل بدون جفت پذیرفته می‌شود
+
+`POST /inventory/transactions` با نوع `TRANSFER_IN` بدون هیچ TRANSFER_OUT متناظری پذیرفته می‌شود (سرویس آن را افزایش عمومی حساب می‌کند). یعنی از مسیر API می‌توان «ورودی انتقال» جعلی ثبت کرد. فقط جفتِ واقعیِ ساخته‌شده توسط خود سرویس `transfer_pair_id` دارد.
+
+**پیشنهاد:** TRANSFER_IN از مسیر عمومی بسته شود (فقط از طریق جفت‌سازی داخلی سرویس ثبت شود).
+
+## ۴. 🟡 create انتقال بین‌کارگاهی «ردیف انبار» نمی‌گیرد
+
+`POST /inventory/project-transfers` به‌جای `inventory_row_id` فقط material/brand/unit/specs می‌گیرد؛ اگر match دقیق پیدا نشود، سرویس با fallback امتیازدهی «بهترین کاندیدای همان متریال» را کسر می‌کند (`project_transfer_service.py:105-151`). اگر یک متریال با چند ردیف specs نزدیک به هم باشد، ممکن است از ردیفی غیر از قصد کاربر کسر شود.
+
+**پیشنهاد:** پذیرش `inventory_row_id` اختیاری در payload و کسر دقیق از همان ردیف.
+
+## ۵. 🟡 Audit Trail ناقص است
+
+فقط `POST /inventory/transactions` رکورد audit می‌نویسد (`inventory.py:491-500`). این‌ها audit ندارند:
+- ساخت / ویرایش (PATCH) / لغو (DELETE) انتقال بین‌کارگاهی
+- تأیید تحویل PM (`/pm/receipts` و دریافت انتقال)
+- CRUD انبارها و تغییرات کاربران
+
+**پیشنهاد:** گسترش `audit_record` به این مسیرها (helper موجود آماده است و هرگز raise نمی‌کند).
+
+## ۶. 🟡 فیلدهای الزامی کلیدی فقط در UI اعمال می‌شوند
+
+- `delivered_to` (تحویل‌گیرنده برداشت) در UI اجباری است؛ API بدون آن 201 می‌دهد.
+- ظرفیت‌سنجی مشابه برای «توضیح» (note) شمارش موجودی و… .
+
+## ۷. 🟡 رفتار postSeq قدیمی هنگام خطای وسط بچ
+
+در بخش‌های لیستی ساده (برداشت/ضایعات/اتلاف/مفقودی/انتقال داخلی) اگر ثبت ردیف kام شکست بخورد، ردیف‌های ۱..k-1 **موفق ثبت‌شده** در جدول باقی می‌مانند → retry کاربر = ثبت تکراری. (در انتقال بین‌کارگاهی و برگشتِ این نسخه، ردیف‌های موفق از لیست حذف می‌شوند — الگوی درست.)
+
+**پیشنهاد:** انتقال الگوی «حذف ردیف موفق + خطای inline» به postSeq.
+
+## ۸. 🟡 برگشت‌های قدیمی بدون REF قابل انتساب دقیق نیستند
+
+برگشت‌های ثبت‌شده قبل از این نسخه هیچ اشاره‌ای به برداشت مرجع ندارند. UI با تخصیص FIFO بین برداشت‌های هم‌ردیف (متریال+برند+مشخصات+واحد) جبران می‌کند، ولی این حدس است و در دو حالت خطا دارد:
+- برگشت قدیمی به انباری غیر از انبار مبدأ → قابل انتساب نیست و از مانده کم نمی‌شود.
+- تخصیص FIFO صفحات اولِ واکشی ممکن است برگشتِ متعلق به برداشتِ صفحه‌های بعد را جابه‌جا کند.
+
+**پیشنهاد (داده):** اسکریپت یک‌باره‌ی backfill — تطبیق برگشت‌های قدیمی با برداشت‌های همان ردیف (قدیمی‌ترین برداشتِ باقیمانده) و درج REF در note.
+
+## ۹. 🔵 معناشناسی تاریخ فیلترها = UTC (نه تهران)
+
+فیلتر `date_from/date_to` (بعد از اصلاح مورد ۱) مرز روز را در UTC می‌برد، در حالی که UI جلالی و ساعت کاربر +03:30 است. برداشت ساعت ۰۰:۰۰–۰۳:۳۰ تهران در «دیروز» UTC می‌افتد. این معناشناسی قدیمی حفظ شد؛ اگر روزِ تهران ملاک است، باید offset منطقه (یا پارامتر `tz` از کلاینت) اضافه شود.
+
+## ۱۰. 🔵 GET /inventory/{id}/transactions enrichment ناقص
+
+پاسخ این endpoint فیلدهای material/brand/specs/unit را ندارد (فقط GET لیست کامل enrich می‌کند). UI فعلی از آن استفاده نمی‌کند ولی برای دیباگ/گزارش‌ها گمراه‌کننده است.
+
+## ۱۱. 🔵 سقف ۱۰۰ رکوردی واکشی‌های لیست
+
+`GET /inventory` و lookup ها در `useInventoryData` با `page_size=100` واکشی می‌شوند؛ انبار با بیش از ۱۰۰ رکورد موجودی در UI کامل نمایش داده نمی‌شود (محدودیت قدیمی، در لیست‌های جدید این صفحه هم از همان دیتا می‌خواند). لیست برگشت و مفقودی‌ها صفحه‌بندی/واکشی کامل دارند.
+
+## ۱۲. 🔵 لیست انتقال‌های بین‌کارگاهی بدون صفحه‌بندی
+
+`GET /inventory/project-transfers` و `/pm/transfers/on-the-way` همه‌ی ردیف‌ها را بدون pagination برمی‌گردانند؛ با رشد داده بار پاسخ زیاد می‌شود.
+
+---
+
+## چیزهایی که بررسی شد و درست است ✅
+
+- **Immutable Ledger در سطح API:** برای تراکنش‌ها هیچ endpoint ویرایش/حذفی وجود ندارد (فقط POST و GET). تنها حذفِ موجود، لغو انتقال بین‌کارگاهی است که تراکنش خروجی خودش را بازمی‌گرداند و موجودی را ترمیم می‌کند.
+- **سقف FOUND در بک‌اند اعمال می‌شود:** بیش از «Σ|LOSS| − ΣFOUND» همان ردیف → 422 (تست شد).
+- **STOCK_COUNT فقط روی رکورد موجود** و با ثبت اختلاف علامت‌دار صحیح.
+- **TRANSFER_OUT جفتی:** کسر مبدأ و ایجاد TRANSFER_IN مقصد با `transfer_pair_id` مشترک و قفل ردیف؛ موجودی منفی نمی‌شود.
+- **دریافت انتقال بین‌کارگاهی:** مجموع allocations باید دقیقاً برابر مقدار انتقال باشد و انبارها به پروژه مقصد تعلق داشته باشند.
+- **هویت ردیف انبار** با `specs_hash` (SHA256 مرتب‌شده‌ی specs) و sentinel برند NULL یکتاست — ریسک ادغام رکوردهای متفاوت وجود ندارد.
