Address round-3 CodeRabbit findings

[nitrobass24]

Third round of CodeRabbit findings on PR #467 (develop → master). All 6 verified valid against current code; all fixed. Test + CHANGELOG only.

Acted on (6 of 6)

#	File	Change
1+2	CHANGELOG.md (0.18.0 entry)	Reorder sections to Changed → Added → Fixed per CLAUDE.md's documented order. Fold the standalone "Tests" block into Added as a single bulleted item with sub-bullets — "Tests" wasn't an allowed section name
3	path-pairs.service.spec.ts (snapshot())	Pipe through take(1) before subscribing so the helper auto-completes after one emission instead of leaking subscribers on service.pairs$
4	version-check.service.spec.ts	Assert notifications.toHaveLength(1) before indexing notifications[0].text so an empty array gives a clear failure
5	integrations.spec.ts ("Delete Me" poll)	Throw on !res.ok inside the poll callback instead of returning undefined — returning undefined was falsely satisfying toBeUndefined() and masking real API errors
6	settings.spec.ts (3 sites)	Add explicit { timeout: 5000 } to the SSE-gated toBeEnabled() calls at lines 185, 226, 408. Matches the established text-field pattern at line 43 (where the canonical "text field change saves to backend" test sets the same timeout)
7	test_web_app_job.py (error test)	Mirror the happy-path assertion: capture log_ctx, then assertTrue(any(\"POST\" in o and \"/fail\" in o and \"500\" in o for o in log_ctx.output)). Confirmed against _RequestLoggingMiddleware.__call__'s finally block that logs method path status duration regardless of exception

Validation

• ruff format --check clean (189 files already formatted)
• ruff check clean ("All checks passed!")
• python3 -m py_compile of touched files clean
• TS diagnostics: only the pre-existing unused-page-parameter at unrelated line 166

Out of scope (still tracked)

The 4 production-code findings in #469 (handler error handling and persistence ordering) remain deferred to their own focused PRs.

📝 Walkthrough

Walkthrough

Multiple test files are updated to improve robustness: Angular service tests now properly close subscriptions and verify assertion counts, Playwright E2E tests add explicit timeouts and throw on API errors, a Python test verifies logged output, and CHANGELOG.md documents the expanded test coverage added in the release.

Changes

Test Robustness and Reliability Improvements

Layer / File(s)	Summary
Angular Service Tests src/angular/src/app/services/settings/path-pairs.service.spec.ts, src/angular/src/app/services/utils/version-check.service.spec.ts	snapshot() helper adds take(1) to prevent subscription accumulation; URL notification test adds explicit notification count assertion before checking content.
E2E Test Reliability src/e2e-playwright/tests/integrations.spec.ts, src/e2e-playwright/tests/settings.spec.ts	Integration delete test throws on API non-OK responses instead of returning undefined; Settings tests add explicit { timeout: 5000 } waits for form field enablement before interaction.
Python Test Coverage src/python/tests/unittests/test_web/test_web_app_job.py	Error-path middleware test now captures and verifies logged HTTP method, path, and status code when the wrapped app raises an exception.
Release Documentation CHANGELOG.md	0.18.0 release notes move test coverage bullets from standalone ### Tests subsection into expanded ### Added section.
