feat: Add notes feature to highlights (#2154)

* feat: Add note-taking functionality to highlights

This commit adds the ability to add and edit notes on highlights, allowing users to capture their thoughts alongside highlighted text.

Changes:
- Updated zUpdateHighlightSchema to include optional note field
- Modified Highlight.update() method to persist notes to database
- Added note button (MessageSquare icon) beside color picker in highlight menu
- Implemented note dialog with textarea for adding/editing notes
- Updated Highlight interface to include optional note field
- Modified ReaderView to pass notes through create and update operations
- Enhanced HighlightCard to display notes below highlighted text

The note button appears alongside the color picker for both new and existing highlights. Notes are displayed in a smaller, muted font below the highlighted text in the HighlightCard component.

* refactor: Convert highlight UI to inline form

Changed the highlight creation/editing interface from a modal dialog to an inline form for a more streamlined user experience.

Changes:
- Replaced ColorPickerMenu and Dialog with a unified HighlightForm component
- Form now displays color selector and note textarea together inline
- Added labels for "Color" and "Note" sections
- Textarea is now optional and inline (placeholder: "Add a note (optional)...")
- Consolidated Save and Cancel buttons in the form
- Delete button appears only for existing highlights
- Removed MessageSquare icon - notes are now always visible in the form
- Simplified state management by removing separate dialog state

The form appears in a popover when text is selected or an existing highlight is clicked, showing both color options and note input in a single 320px wide form.

* fixes
