feat(v1.4.0): Checklists feature + WiFi permission cleanup

Features:
- Interactive checklists with tap-to-check, drag & drop sorting
- GitHub-flavored Markdown export (- [ ] / - [x])
- FAB menu for note type selection

Fixes:
- Improved Markdown parsing (robust line-based content extraction)
- Better duplicate filename handling (ID suffix)
- Foreground notification suppression

Privacy:
- Removed ACCESS_WIFI_STATE and CHANGE_WIFI_STATE permissions
  (SSID binding was never used, app only checks connectivity state)

Code Quality:
- Fixed 7 Detekt warnings (SwallowedException, MaxLineLength, MagicNumber)
