Thomas Farstrike 7679db3607 Refactor camera code: DRY, fix memory leak, improve error handling 
- Extract RGB conversion helper to eliminate duplication
  - Unify save functions
  - Fix buffer cleanup on error (memory leak)
  - Move retry logic into init_internal_cam()
  - Add error handling for failed camera reinitialization
  - Consolidate button sizing with class variables
  - Remove redundant initialization and unnecessary copies

Thomas Farstrike 7e4585e91e Camera: support more resolutions 
It's a bit unstable, as it crashes if the settings button is clicked after startup,
but not when closing and then re-opening. Seems to work for 640x480, including QR decoding.
