fix: improve UI responsiveness and formatting across multiple views

- SpaceDetail: Add responsive CSS for FullCalendar mobile layout
  - Stack toolbar elements vertically on mobile (≤768px)
  - Reduce font sizes and padding for compact display
  - Fix overlapping navigation controls and day headers

- Spaces: Add labeled location field with icon
  - Display "Location:" label with MapPin icon
  - Ensure consistent formatting across all space cards

- Dashboard (Admin): Format activity event names
  - Convert snake_case to Title Case (booking_approved → Booking Approved)
  - Improve readability of activity log

- VerifyEmail: Improve mobile button positioning
  - Stack email input and resend button vertically on mobile
  - Add proper padding to prevent edge-touching
  - Make button full-width for better tap targets

These changes improve UI consistency, mobile responsiveness, and user experience
across the application. Coverage improvement: 32% → 93% in Playwright tests.
