feat(admin): improve styling, light mode fixes, filter & pagination for members

- Member page: add role/status filters and pagination (like movie page)
- Member table: match movie table style (centered columns, #eeee borders)
- AdminToggle: change from yellow to CineK Blue (#095DF2)
- Sort icons & pagination: use CineK Blue instead of yellow
- Light mode: fix dropdowns/modals dark bg, narrow text-white override
- Sidebar: white background with proper light-mode colors
- Sync dialog: convert from dark to light mode theme
