…gnifier improvements

- Add MouseClickHighlighterController with theme-colored animated rings
  that replace system click indicators for display/region recordings
- Add in-overlay camera shape switching (rectangle/rounded/circle) via
  hover-revealed controls on the camera overlay panel
- Improve screen magnifier: larger capture area, fix coordinate system
  to use points instead of pixels for sourceRect, exclude self-window
  from capture to prevent hall-of-mirrors effect
- Extract ScreenMagnifierController.sourceRect as static method and
  add unit tests for centering and edge clamping
- Expand RecordingService.apply to accept full AppSettings for access
  to theme and other settings beyond recording-specific ones
