Improve API token format and enhance auth status command

- Change token format to reviq_<base58> prefix instead of raw hex
- Add me.authStatus API endpoint for detailed auth information
- Enhance CLI `reviq auth status` to show token details from API
- Add comprehensive tests for token generation (18 tests)
- Extract bootstrap logic to @reviq/db for reusability and testing
- Remove default db export; callers must use createDb() directly

Token changes:
- New format: reviq_<base58-encoded-32-bytes>
- Added parseToken() for validation
- Added isValidTokenFormat() helper

Auth status endpoint returns:
- User profile information
- Auth method (api_token or session)
- Token/session details (name, expiration, last used)
