feat: Add dual-mode translation workflow for PR testing

Enhanced the translation workflow to support two operational modes:

## 🧪 Testing Mode (NEW)
- Triggers on every PR commit
- Triggers on push to claude/** and translations/** branches
- Updates .ts file directly in current branch
- Does NOT create new PRs
- Provides immediate feedback during development
- Perfect for validating translation extraction

## 🚀 Production Mode (Existing)
- Triggers weekly (Sunday midnight UTC)
- Triggers on manual workflow dispatch
- Creates new branch (translations/auto-update-YYYYMMDD-HHMMSS)
- Creates Pull Request for review
- Isolated translation updates

## Key Features
- Automatic mode detection based on event type
- Enhanced logging with emojis and clear status
- Diff stats showing translation changes
- Summary output for both modes
- Path-based triggers (.cpp, .h, .qml, .ui, .ts files)

## Benefits
Testing Mode:
✅ No extra PRs during development
✅ Keeps translations in sync with code changes
✅ Immediate validation of workflow
✅ Easy to review changes in context

Production Mode:
✅ Weekly automation ensures completeness
✅ Clean separation of translation work
✅ Easy for translators to review
✅ Professional PR with full context

## Documentation
Added comprehensive TRANSLATION-WORKFLOW.md covering:
- Detailed explanation of both modes
- Trigger conditions and examples
- Workflow output samples
- Usage guide for developers, translators, maintainers
- Troubleshooting section
- Best practices
- Weblate integration notes

This allows testing the workflow in PRs while maintaining
clean automated weekly updates for translators.
