fix(tests): resolve test failures in PR #493

Backend:
- Remove unnecessary mock stubbings for skillId 2 and 3 in MySkillAppServiceTest.listMySkills_combinesKeywordNamespaceAndStatusFilters
- The test filters results to only return skill with id=1, so mocks for id 2 and 3 were never called, causing UnnecessaryStubbingException

Frontend:
- Add missing mocks for useLocation, useSearch, useMyNamespaces, and useDebounce in my-skills.test.ts
- MySkillsPage component uses these hooks but the test setup didn't provide mocks, causing 'No QueryClient set' and 'No export' errors

All 4 frontend tests now pass locally.
