feat: home/lock widgets, Health-aware streaks, workout editor, and entitlement fixes

Widgets (new KisaniCalWidgets extension)
- Event Countdown widget: configurable via AppIntent, pick from your events
  or set a custom name/date; dot-grid progress toward the event.
- Day Progress and Tasks-Done-Today widgets; lock screen widgets.
- Shared dot grid sizes circles to fill the widget evenly at any count.
- Tasks/calendar prefs now persist to the App Group so widgets read live data.

Health & streaks
- Persist HealthKit authorization and re-establish on launch (fixes the
  Today dashboard and streak sync disappearing after relaunch).
- Add a Health permission toggle to onboarding; unify Settings/Profile on the
  manager's state.
- Day streak counts from a logged Health workout OR marking all exercises
  complete; nudge to mark exercises complete even when Health logged the workout.

Workout editor
- Drag to reorder exercises and move them across sections (drag-and-drop);
  swipe to delete.
- Add-exercise sheet: global search and keep-adding-multiple with a running count.

Fixes
- Restore app entitlements link (Sign in with Apple, HealthKit, App Group, iCloud).
- Add HealthKit usage strings; widget Info.plist NSExtension + nested bundle id.
- Calendar "Connect" routes to Settings when access was denied.
- Bake DEVELOPMENT_TEAM and shared versions into project.yml.
