feat: improve TaskCard and TagList components, enhance task loading logic

- Updated TaskCard to conditionally render footer elements based on available data (due date, source, completion status).
- Enhanced TagList to visually indicate deleting tags and improved button styles for better UX.
- Modified useTasks hook to refresh tasks only if no initial data is present, optimizing loading behavior.
- Updated TagsPageClient to manage local tags and handle optimistic UI updates during tag deletion.
