fix(test): tighten log-work assertions, repair summarise.test.ts for source exclusion, add owner-only UI check

Critical fixes to test suite:

1. Fix time bomb in summarise.test.ts: Task 4 changed summaryStatus filter to exclude source="manual",
   so the assertion would fail once any manual entry exists. Updated test to count only non-manual
   commits and added coverage proving manual entries are excluded.

2. Tighten log-work metrics assertions from toBeGreaterThanOrEqual to exact equality (toBe).
   The old assertions would miss if manual entries were incorrectly fed into session clustering.
   Use a fresh baseline recompute to catch regression of Task 2's manual exclusion fix.

3. Add recomputeMetrics call in afterAll to restore cache after test cleanup,
   preventing inflated dashboard metrics on the demo project.

4. Fix fixture link_source from "none" to "manual" to match actual logWorkAction behavior
   (Task 6 review fix).

5. Add UI coverage: "Log work" button is owner-only, verifying the security model.
