- Localization updates for all supported languages (ar, bg, de, en, es,
fr, id, it, ja, pt-br, ru, vi, zh-traditional, zh)

### What problem does this PR solve?
This PR adds comprehensive **Right-to-Left (RTL) language support**,
primarily targeting Arabic and other RTL scripts (Hebrew, Persian, Urdu,
etc.).
Previously, RTL content had multiple rendering issues:
- Incorrect sentence splitting for Arabic punctuation in citation logic
- Misaligned text in chat messages and markdown components
- Improper positioning of blockquotes and “think” sections
- Incorrect table alignment
- Citation placement ambiguity in RTL prompts
- UI layout inconsistencies when mixing LTR and RTL text
This PR introduces backend and frontend improvements to properly detect,
render, and style RTL content while preserving existing LTR behavior.
#### Backend
- Updated sentence boundary regex in `rag/nlp/search.py` to include
Arabic punctuation:
- `،` (comma)
- `؛` (semicolon)
- `؟` (question mark)
- `۔` (Arabic full stop)
- Ensures citation insertion works correctly in RTL sentences.
- Updated citation prompt instructions to clarify citation placement
rules for RTL languages.
#### Frontend
- Introduced a new utility: `text-direction.ts`
- Detects text direction based on Unicode ranges.
- Supports Arabic, Hebrew, Syriac, Thaana, and related scripts.
- Provides `getDirAttribute()` for automatic `dir` assignment.
- Applied dynamic `dir` attributes across:
- Markdown rendering
- Chat messages
- Search results
- Tables
- Hover cards and reference popovers
- Added proper RTL styling in LESS:
- Text alignment adjustments
- Blockquote border flipping
- Section indentation correction
- Table direction switching
- Use of `<bdi>` for figure labels to prevent bidirectional conflicts
#### DevOps / Environment
- Added Windows backend launch script with retry handling.
- Updated dependency metadata.
- Adjusted development-only React debugging behavior.

Closes#12803
### What problem does this PR solve?
The chat input textarea in the Chat UI (and Embed UI) has a fixed height
and cannot be resized, causing poor UX when users type messages longer
than 2 sentences. The input becomes cramped and difficult to read/edit.
**Root cause:** The `Textarea` component in
[NextMessageInput](cci:1://file:///ragflow/web/src/components/message-input/next.tsx:62:0-290:1)
had `resize-none` and `field-sizing-content` CSS classes that prevented
resizing, and the existing `autoSize` prop was not being utilized.
**Solution:**
- Removed `resize-none` and `field-sizing-content` classes
- Added `autoSize={{ minRows: 1, maxRows: 8 }}` to enable auto-expand
- Added `max-h-40` class to limit maximum height to 160px
The textarea now auto-expands from 1 to 8 rows as users type longer
messages.
