feat(02-03): add expand/collapse and inline editing to EntryCard

- Add expanded state for expand/collapse toggle
- Implement inline editing for title, content, and type
- Add 400ms debounced auto-save using fetch to ?/update
- Show 'Saving...' indicator during save
- Add delete button with confirmation dialog
- Use Svelte slide transition for smooth expand/collapse
- Fix button nesting by restructuring layout
