✨ feat(tables): add "No Results" empty state for all table components

Add consistent empty state handling across all table components to improve
user experience when search/filter results are empty.

Changes:
- Import Empty component and IllustrationNoResult/IllustrationNoResultDark from @douyinfe/semi-ui
- Add empty prop to Table components with "搜索无结果" message
- Support both light and dark theme illustrations
- Apply internationalization support for empty state text

Affected files:
- web/src/components/table/MjLogsTable.js
- web/src/components/table/LogsTable.js
- web/src/components/table/ChannelsTable.js
- web/src/components/table/RedemptionsTable.js
- web/src/components/table/TaskLogsTable.js
- web/src/components/table/TokensTable.js
- web/src/components/table/UsersTable.js
- web/src/components/table/ModelPricing.js

This ensures consistent UX across all table components when no data
matches the current search or filter criteria.
