1. Add `web/src/components/common/ui/CardTable.js`
   • Renders Semi-UI `Table` on desktop; on mobile, transforms each row into a rounded `Card`.
   • Supports all standard `Table` props, including `rowSelection`, `scroll`, `pagination`, etc.
   • Adds mobile pagination via Semi-UI `Pagination`.
   • Implements a 500 ms minimum, active Skeleton loader that mimics real column layout (including operation-button row).

2. Replace legacy `Table` with `CardTable`
   • Updated all major data pages: Channels, MJ-Logs, Redemptions, Tokens, Task-Logs, Usage-Logs and Users.
   • Removed unused `Table` imports; kept behaviour on desktop unchanged.

3. UI polish
   • Right-aligned operation buttons and sensitive fields (e.g., token keys) inside mobile cards.
   • Improved Skeleton placeholders to better reflect actual UI hierarchy and preserve the active animation.

These changes dramatically improve the mobile experience while retaining full functionality on larger screens.
