Improve note deletion UX with double-click confirmation

- Replaced confusing browser confirm() dialog with double-click to delete
- First click highlights delete button in red (confirmation state)
- Second click within 3 seconds actually deletes the note
- Visual feedback with red background on confirmation state
- Tooltip changes to 'Click again to confirm deletion'
- Removed debug logging from delete handlers
- Much clearer and more intuitive deletion flow
