feat(extension): Allow writing notes directly in the extension (#2104)

* feat(extension): add notes editor to bookmark hoarded screen

Adds the ability to directly add and edit notes for bookmarks in the browser extension's hoarded screen (the page shown after saving a bookmark).

Changes:
- Created Textarea UI component for the browser extension
- Created NoteEditor component that uses useUpdateBookmark hook
- Added Notes section to BookmarkSavedPage, displayed between the header and tags
- Notes auto-save when the user clicks away from the textarea (onBlur)
- Shows saving state and error messages to the user

This brings feature parity with the web app's notes functionality.

* add explicit button

* more fixes
