feat: add clickable settings links to checkpoint timeout warnings

- Use flag-based approach instead of passing i18n keys around
- Backend sends warning type enum (WAIT_TIMEOUT/INIT_TIMEOUT) + timeout value
- Frontend CheckpointWarning maps type to appropriate i18n key
- Add checkpoint error translations to webview-ui locale files only
- Remove duplicate translations from backend locale files
- Trans component handles translation and link interpolation
- Move periods inside settingsLink tags for proper spacing

TEMPORARY: Warning always shows for testing (will be reverted)

This provides a clean architecture where:
- Backend: Sends simple flag + timeout (no i18n dependency)
- Frontend: Handles all i18n logic with Trans component
- No duplication: Translations only in frontend where they're used

Addresses PR #8019 review feedback.
