feat: GIF search (Klipy), stickers, emoji picker, and bug fixes

- Add GIF search powered by Klipy API with correct response mapping
  (file.sm/hd tiers, not flat files structure)
- Add sticker system: packs, upload with auto-downscale, send in messages
- Add tabbed InputPopover with emoji, GIF, and sticker pickers
- Fix GIF API key migration race condition (column-add loop vs rename)
- Fix masked API key corruption on settings save (server + client guards)
- Fix sticker packs 403 (reversed isMember parameter order)
- Fix emoji picker not filling popover width (perLine 8→9, CSS 100%)
- Add error logging for Klipy API failures
