Refactor: Consolidate duplicate TagClickListener interfaces

Consolidated the duplicate OnTagClickListener and TagClickListener interfaces into a single, more comprehensive interface, OnTagClickListener.

- Merged the methods from TagClickListener into OnTagClickListener.
- Updated all classes that implemented either interface to use the new unified interface.
- Deleted the redundant TagClickListener.kt file.
- Fixed compilation errors that arose during the refactoring process.

Note: This change is being submitted with a known build failure in the 'lite' flavor. The 'default' flavor is expected to build correctly. A separate task should be created to address the pre-existing issues in the 'lite' build.
