Add missing test coverage for MeilisearchService, AnalyticsCryptoService, AccountController and AdminController

- MeilisearchServiceTest: add test for invalidateSearchCache()
- AnalyticsCryptoService: mark unreachable tryDecryptJsFormat guard
  with @codeCoverageIgnore (decrypt already checks strlen >= 28)
- AccountControllerTest: add test for tickets search query (tq param)
- AdminControllerTest: add test for infra page with snapshot data file
