fix: add iframe title and fix setTimeout memory leak in SuggestionPanel

[khushboo-khatoon]

Summary

Fixed two issues in SuggestionPanel.tsx related to accessibility
and memory leak.

Changes

Bug 1 — Added title to Spotify iframe

Spotify <iframe> was missing a title attribute. Screen readers
could not describe what the iframe contains to visually impaired users.

Added title="Spotify Soundscape Player" to the iframe.

Bug 2 — Fixed setTimeout memory leak in handleSaveNotes

setTimeout inside handleSaveNotes was never cleared. If user
navigates away before 1 second, component unmounts but timeout still
fires and tries to update state on unmounted component.

Moved setTimeout into a useEffect with proper cleanup using
clearTimeout on unmount.

Files Changed

• SuggestionPanel.tsx

Testing

• Lighthouse accessibility score no longer flags missing iframe title
• Screen readers can now correctly describe the Spotify player
• No React warning about state update on unmounted component
• Saving notes and navigating away immediately no longer causes memory leak

Fixes #283
