/** |

* Optimized Classifications Table Class |
| 9 |
* |
| 10 |
* Consolidates multiple classification tables (Categories, Activities, Destinations) |
| 11 |
* into a single flexible system using a type-based approach. This eliminates redundancy |
| 12 |
* and provides a unified interface for all classification needs. |
| 13 |
* |
| 14 |
* Consolidated from: |
| 15 |
* - yatra_trip_categories |
| 16 |
* - yatra_activities |
| 17 |
* - yatra_destinations |
| 18 |
* - yatra_difficulty_levels |
| 19 |
* - yatra_traveler_categories |
| 20 |
* |
| 21 |
* Key improvements: |
| 22 |
* - Single table for all classification types |
| 23 |
* - Type-based differentiation |
| 24 |
* - Hierarchical support via parent_id |
| 25 |
* - JSON metadata for flexible extensions |
| 26 |
* - Unified search and filtering |
