feat: wire up note deletion in analysis page

[zzzhizhia]

Summary

• Connect the existing note deletion backend (API route, client function, DB layer) to the frontend UI
• Add handleDeleteNote callback in the analysis page that calls the API, removes the note from state, and shows a toast
• Thread onDeleteNote prop through RightColumnTabs to NotesPanel so the hover trash icon works

Changes

• app/analyze/[videoId]/page.tsx: Import deleteNote, add handler, pass prop
• components/right-column-tabs.tsx: Add onDeleteNote to props interface and forward to NotesPanel

Test plan

• Navigate to a video with saved notes
• Hover over a note card — trash icon should appear
• Click trash icon — note should be deleted and removed from the list
• Verify toast notification shows "Note deleted"
• Verify error toast shows if deletion fails (e.g. network error)

Pull request overview

This PR wires the existing note deletion capability into the Analyze page UI by threading a deletion callback down to the notes list component and updating local note state when a delete succeeds.

Changes:

• Import and use deleteNote in the Analyze page via a new handleDeleteNote callback (API call, state update, toasts).
• Add onDeleteNote to RightColumnTabs props and forward it to NotesPanel.
