## Summary by CodeRabbit

- **New Features**
  - Introduced a Meetings welcome page with a beta disclaimer and "Get Started" flow.
  - Added separate toggles for AI auto summary and AI auto todo list in meeting settings.
  - Added "Beta" labels to relevant settings and sidebar items for clearer feature status.
  - Enhanced settings UI with improved headers, subtitles, and new styling.

- **Improvements**
  - Meeting settings now allow independent control over AI-generated summaries and todo lists.
  - Updated internationalization to support new meeting and AI transcription features, including richer prompts and hints.
  - Refined logic for enabling meeting recording, including improved permission handling.
  - Simplified transcription logic to rely solely on AI enablement flag.

- **Bug Fixes**
  - Fixed display and control of meeting settings based on beta disclaimer acceptance.

- **Chores**
  - Updated localization files and completeness percentages for several languages.
  - Removed deprecated feature flag for enabling meetings.
