feat(quotes): lock quotes with posted receipts; per-item target project + title dedup

Quotes that already have warehouse receipts can no longer be edited or rolled back:
- backend: quote_has_receipts() guard — replace_quote_children and every backward status transition now return 409 with «این پیشنهاد به‌دلیل ثبت رسید در انبار، غیرقابل ویرایش یا بازگشت است.»
- reopening to «offered» additionally clears item_decisions.project_id (the purchased-project link belongs to acceptance, not to a reopened offer)
- frontend EditModal: hasReceipts locks the whole form — disabled inputs and date pickers (JalaliDatePicker/NumberInput/MilestoneRow/MultiSelectCombobox gained disabled support), add/remove controls for items, termsheets and milestones hidden, status change blocked, amber warning banner; quote deletion now goes through a confirmation dialog (useDeleteQuote)
- date-only semantics: JalaliDatePicker keeps/emits YYYY-MM-DD when withTime=false (typing, «امروز», day selection) and toDateOnly no longer mangles pure date strings

Per-item target project (candidate projects stay intact):
- expand_service exposes the decision target project (decision.project + line_item.target_project)
- the accept payload derives item_decisions.project_id from that target project and sends item_projects: [] so line_item_projects keeps the original candidates untouched
- AcceptModal/EditModal select the target project per line item

Material titles:
- quoteUtils.formatMaterialTitle() composes one normalized, deduplicated «name + brand + specs» title, replacing materialLabel/materialSpecs/specsLabel usage across dashboard cards, quote detail and the modals

Verified: python compile + api/frontend image builds (tsc + vite) clean.
