test(e2e): fix failing and flaky supersync archive conflict tests

Three separate root causes addressed:

1. markTaskDone/markSubtaskDone race with 200ms animation delay:
   toggleDoneWithAnimation uses window.setTimeout(200ms) before
   dispatching isDone:true. Tests proceeded before the state settled,
   causing subsequent assertions to fail. Fix: wait for isDone CSS class
   after clicking done-toggle. Also use .first() on the task locator to
   avoid Playwright strict-mode violations during CDK drag animation,
   where the same task briefly exists as two DOM elements.

2. Premature waitForURL resolution in supersync.spec.ts test 5.1:
   waitForURL(/tag\/TODAY/) matched the current /tag/TODAY/daily-summary
   URL immediately. Fix: add negative lookahead (?!\/daily-summary).

3. LWW worklog title nondeterminism in archive-conflict test:
   After archive-wins conflict resolution and multiple sync rounds, the
   archived task title on both clients depends on sync timing — it may be
   the original name or the renamed name. Fix: accept either title using
   hasTaskInWorklog OR, rather than asserting a specific title.
