feat(testing): add ShowAllCard component testing with 100% coverage

- Implements comprehensive unit tests covering all 10 required categories
- Creates three-tier mock architecture (Simple/Standard/Complex)
- Achieves 100% coverage across statements, branches, functions, and lines
- Includes performance testing, snapshot testing, and mock integration
- Demonstrates established testing patterns and mock architecture
- Adds 52 new tests to testing suite

Component: ShowAllCard.vue (66 lines)
Coverage: 100% (statements, branches, functions, lines)
Tests: 52 comprehensive tests
