♻️ refactor(components): restructure RedemptionsTable to modular architecture

Refactor the monolithic RedemptionsTable component (614 lines) into a clean,
modular structure following the established tokens component pattern.

### Changes Made:

**New Components:**
- `RedemptionsColumnDefs.js` - Extract table column definitions and render logic
- `RedemptionsActions.jsx` - Extract action buttons (add, batch copy, clear invalid)
- `RedemptionsFilters.jsx` - Extract search and filter form components
- `RedemptionsDescription.jsx` - Extract description area component
- `redemptions/index.jsx` - Main container component managing state and composition

**New Hook:**
- `useRedemptionsData.js` - Extract all data management, CRUD operations, and business logic

**New Constants:**
- `redemption.constants.js` - Extract redemption status, actions, and form constants

**Architecture Changes:**
- Transform RedemptionsTable.jsx into pure table rendering component
- Move state management and component composition to index.jsx
- Implement consistent prop drilling pattern matching tokens module
- Add memoization for performance optimization
- Centralize translation function distribution

### Benefits:
- **Maintainability**: Each component has single responsibility
- **Reusability**: Components and hooks can be used elsewhere
- **Testability**: Individual modules can be unit tested
- **Team Collaboration**: Multiple developers can work on different modules
- **Consistency**: Follows established architectural patterns
