Fix viewer review findings

- Reels paging: drop page callbacks after destroy or a replaced playlist
- Scope Glide loads to views and clear them in onDestroy (no deprecated Glide.with(Activity))
- Stop the player in onStop, re-prepare in onStart
- Photo timer uses real elapsed time and starts when the photo is on screen
- Reels: continue past the old last post when a new page arrives; "No reels" when empty
- Likes: ordered single-thread executor, newer toggle wins on error, no "null" in toast
- Note the unbounded frame grab limitation
