[Remove Vuetify from Studio] Convert content library filter bar unit tests to Vue Testing Library

[sharma-anushka]

Summary

Converted Content Library (CatalogFilterBar) unit tests from Vue Test Utils to Vue Testing Library.

Key Changes

• Replaced mount() and wrapper.vm usage with Vue Testing Library’s render() and semantic queries
• Removed direct calls to component methods (resetKeywords, resetCoach, removeLanguage)
• Tests now simulate real user interactions (clicking buttons and filter chips)
• Router state is validated through actual navigation updates instead of manual mutation
• Eliminated assertions on internal computed state (currentFilters)
• Improved test resilience by asserting only user-observable behavior

Test Coverage

• Clear all filters via UI interaction
• Remove text-based filters (keywords)
• Remove boolean-based filters (coach)
• Remove list-based filters incrementally (languages)
• Ensure unrelated query parameters remain unaffected
