Replace the floating upload toast with a notification bell in the top bar
(between language selector and user avatar). All upload progress, completion,
and quota errors now flow through the bell dropdown panel.
- Add notification bell button with animated badge counter
- Dropdown panel shows per-file upload progress bars and overall batch progress
- Bell rings on new notifications when panel is closed
- Upload success/error states with color-coded icons
- Quota exceeded errors shown as notification items
- Clear all button to dismiss notifications
- Panel auto-opens when upload starts
- Full dark mode support
- Mutual exclusion with user menu (opening one closes the other)
- i18n keys for en/es (notifications.title, notifications.empty)
- SW cache bump to v10
