fix(dvr): add DB retry resilience, fix recording card logos, prevent incorrect artwork
Add exponential backoff retry (_db_retry helper) for transient DB errors during final metadata save, startup recovery, and initial TS proxy connection. Add FFmpeg remux retry for transient I/O errors. Retry same proxy base before falling back to next candidate on initial connection failure. Fix DVR card logos not displaying: channel summary API returns logo_id (integer) but frontend expected a nested logo object with cache_url. Add getChannelLogoUrl() helper that handles both data shapes. Backend artwork prefetch and run_recording now fall back to the channel's own logo when no show-specific artwork is found, ensuring poster_logo_id is always populated. Prevent incorrect artwork by skipping external API searches (TVMaze, iTunes) when no program title is available - channel names like "USA A&E SD*" returned unrelated results from fuzzy matching. Add 13 tests for retry logic (test_dvr_retry.py)
