fix #2758, fix #2742: implement year and season search filters

[MasenWen]

Summary

This PR adds time-based search filters and several desktop/player UX improvements.

Search

• add year and season filters to subject search
• place the time filter controls alongside the existing search filters in the search UI
• support anime season semantics for:
  • January season
  • April season
  • July season
  • October season
• wire the selected year/season through search state and repository query building

Player / Desktop UX

• add global desktop zoom controls with:
  • Ctrl + Mouse Wheel
  • Ctrl + +
  • Ctrl + -
• prevent windowed mode from shrinking below the normal scale
• improve close request handling for the desktop window

Playback Speed

• keep preset playback speeds up to 2x
• add custom playback speed input
• support values from 0.1x to 5.0x
• validate custom input to one decimal place
• keep the controller visible while the custom speed dialog is open
• fix incorrect custom speed normalization

Media Source Selection

• add a persisted hide dead web sources preference
• update source visibility based on the existing source status detection
• keep the currently selected source visible even when dead-source filtering is enabled
• refresh source visibility together with source retesting

Notes

• the search keyboard navigation out-of-bounds fix is intentionally not included in the issue scope here, since that issue is already being handled separately
• custom playback speed UI was implemented in a separate component to avoid destabilizing the original progress/controller implementation

Manual Testing

• verified search year/season filtering behavior
• verified desktop zoom shortcuts
• verified playback speed preset and custom input behavior
• verified custom speed dialog no longer closes unexpectedly during interaction
• verified dead-source filtering toggle and refresh behavior

Build Verification

• :app:desktop:compileKotlin
