feat: Add filtering and searching to governance proposals page

- Added filtering of proposals by status (Draft, Active, Approved, Rejected, Cancelled).
- Added searching of proposals by title and description.
- Improved UI to persist filter and search values.
- Added a "No proposals found" message for better UX.
