refactor: remove approve/reject, add per-asset Postiz push button

- Remove approve/reject buttons and status badge from asset cards
- Remove bulk approve/reject from gallery toolbar
- Remove status filter dropdown (no longer relevant)
- Add "Postiz" button on each image/video asset card for direct publishing
- Keep bulk "Push to Postiz" for multi-select in toolbar
- Update How This Works guide to remove approve/reject section
