🎨 refactor: MultiKeyManageModal: cleaner stats UI, remove chart, integrate toolbar/pagination, and improve UX

- Replace custom dots with Semi Badge types (success/danger/warning); add compact Progress bars
- Remove pie chart and related deps/config; move total key count and mode tags into the modal title
- Rework header using Row/Col; three equal stat cards (enabled/manual-disabled/auto-disabled)
- Integrate toolbar into Table title; wrap content with Card; use Table’s native empty state
- Make “Enable All” conditional (hidden when all keys are enabled), mirroring “Disable All”
- Unify numeric typography (current/total same size) for better readability
- Default page size set to 10; fallback to 10 when backend page_size is absent; page-size options: 10/20/50/100
- Cleanup imports and dead code (remove VChart and pie-spec logic)
- Minor spacing polish (extra bottom margin before table), no footer buttons
