[Code Cleanup] Remove Redundant or Duplicate Code

**Issue:** Duplicate logic/components/functions found across codebase.

**Examples:**
- Repeated `fetch()` logic in multiple components
- Duplicate UI card or layout structures

**Action:**
- Identify and abstract reusable logic/components
- Move to shared `utils/`, `components/`, or `hooks/`

✅ Expected: DRY code and better maintainability
