refactor(i18n): move translations to JSON locale files

- Extract 1149 translation keys from i18n.py into locales/ru.json and locales/en.json
- Rewrite i18n.py as a lightweight JSON loader (5287 → 128 lines)
- Add I18nService.reload() for runtime hot-reload without restart
- Add I18nService.available_languages() to list loaded language codes
- Public API unchanged: t(), get(), get_all(), add_translation()
- New languages require only a new *.json file in locales/ — no code changes

Bump version: 1.1.6 → 1.1.7

+### 🌍 i18n — Translation Files Refactored
+
+- **Translations moved to JSON locale files** — all 1 149 translation keys extracted from the Python source into `backend/app/locales/ru.json` and `backend/app/locales/en.json`
+- **`i18n.py` reduced from 5 287 → 128 lines** — now a lightweight JSON loader with lazy initialisation; zero changes to the public API (`t()`, `I18nService.get()`, `.get_all()`, `.add_translation()`)
+- **Adding a new language requires no code changes** — drop a `xx.json` file into `backend/app/locales/` and it is picked up automatically on next startup
+- **`I18nService.reload()`** — new method that reloads all locale files at runtime without a container restart; useful for live translation editing
+- **`I18nService.available_languages()`** — returns the list of language codes currently loaded from disk

 ### Adding New Language
 
-1. Open `backend/app/i18n.py`
-2. Add translation for each key:
+Translations are stored as flat JSON files in `backend/app/locales/`.
+To add a new language, simply create a new file — no code changes required:
 
-```python
-"key_name": {
-    "ru": "Russian text",
-    "en": "English text",
-    "uz": "O'zbek matni"  # New language
-}
+```bash
+# Create a new locale file for Uzbek
+cp backend/app/locales/en.json backend/app/locales/uz.json
+# Then translate the values in uz.json
 ```
 
+The file name becomes the language code (`uz.json` → `"uz"`). The panel picks
+it up automatically on next startup (or call `I18nService.reload()` at runtime).
+
+> **Structure:** each file is a flat `{"key": "translated string"}` JSON object.
+> Keys must match the existing keys in `ru.json` / `en.json`.
