revert(ui): بازگردانی سه بخش به حالت پیش از UI v1 (کامیت 853ad67)

- دکمهٔ تغییر زبان: کپسول بزرگ دوزبانه → دکمهٔ کوچک آیکون+متن (طرح قبلی)
- ساختار صفحهٔ جزئیات پروژه: بازگشت به چیدمان قبلی (دیتابیس‌محور بود و می‌ماند)
- قالب پرسش‌وپاسخ: بازگشت به چیدمان دوستونه (تیتر کنار آکاردئون)

توجه: بخشی از UI v1 (fatemeh) عمداً برگردانده شده به درخواست تیم UI؛
بقیهٔ تغییرات آن کامیت سر جایش است. ویرایش‌پذیری دیتابیس‌محور پروژه‌ها
و دکمهٔ ویرایش، روی همین ساختار قدیمی دوباره اعمال شده‌اند.
