feat: Add Turkish language support (#5438)

## Summary
- Added complete Turkish language translation for ComfyUI Frontend
- Integrated Turkish locale into the i18n system
- Added Turkish as a selectable language option in settings

## Implementation Details
- Added Turkish translation files provided by @naxci1:
  - `src/locales/tr/main.json` - Main UI translations
  - `src/locales/tr/commands.json` - Command translations
  - `src/locales/tr/nodeDefs.json` - Node definitions translations
  - `src/locales/tr/settings.json` - Settings translations
- Updated `src/i18n.ts` to import and register Turkish locale
- Added Turkish option to language selector in
`src/constants/coreSettings.ts`

## Test Plan
- [ ] Verify Turkish translations load correctly
- [ ] Test language switching to/from Turkish
- [ ] Check all UI elements display properly in Turkish
- [ ] Verify node descriptions and tooltips in Turkish
- [ ] Test command palette in Turkish

Fixes #5437
