Fix the last column (operation/detail columns) to the right side across all table components to improve user experience and ensure important actions remain visible during horizontal scrolling.
Changes:
- ChannelsTable.js: Fix operation column to right
- UsersTable.js: Fix operation column to right
- TokensTable.js: Fix operation column to right
- RedemptionsTable.js: Fix operation column to right
- LogsTable.js: Fix details column to right
- MjLogsTable.js: Fix fail reason column to right
- TaskLogsTable.js: Fix fail reason column to right
All tables now have their rightmost column fixed using Semi Design's `fixed: 'right'` property, ensuring critical information and actions are always accessible regardless of table scroll position.
