feat(notifications): add Open in Anki action and in-place progress updat

- Add openNoteInBrowser to AnkiConnectClient via guiBrowse IPC
- Add Open in Anki action button to mined-card overlay notifications and history entries
- Fall back to a direct AnkiConnectClient when the live integration is unavailable
- Embed notification images as base64 data URIs so history panel shows thumbnails
- Update same-id progress notifications in place to avoid spinner flicker
- Thread noteId through IPC overlay notification action payload
