test: remediate test suite, enable skipped frontend/SSE tests, and add comprehensive unit tests

- Deleted redundant unit test file tests/unit/dashboard.test.js
- Enabled skipped frontend DOM state and API tests in tests/frontend/state.test.js
- Fixed Supertest client socket abort exception in SSE stream integration tests using new graceful testClose parameter
- Consolidated duplicate helpers in server/routes/history.js and server/utils/arrRetrievers.js to unified services TagMatcher and DownloadAssembler
- Added comprehensive unit tests for loadSecrets.js, PollingSonarrRetriever.js, PollingRadarrRetriever.js, and ombiHelpers.js
- Achieved a 100% Vitest pass rate (834/834 tests) with robust code coverage
