* test: add e2e coverage and mock backends for jira and linear integrations
Adds in-memory MockClient + MockController for both integrations gated by
KANDEV_MOCK_{JIRA,LINEAR}=true, plus apiClient mock helpers and Playwright
specs covering settings and import flows.
Also fixes ValidatedPopover's TriggerButton silently dropping radix Slot's
onClick handler — the popover wouldn't open under any synthetic-click path
(including Playwright). Spreads `...rest` onto the inner Button.
Reworks the integration cleanup hook in test-base as an auto fixture so it
runs for every test using the imported `test` object, not just tests in the
fixture file itself.
* fix: address PR review feedback on jira/linear mocks and e2e specs
- Fix SetAuthResult docstrings: nil simulates an unconfigured state, not the default success.
- Drop unused JSON tags from doneTransitionCall and setStateCall (Go-only test fixtures).
- Track Linear issue insertion order so SearchIssues returns deterministic results instead of map-iteration shuffle.
- Document filterByJQL precedence at the SearchTickets call site so the all-hits-on-no-match fallback is visible.
- Wait for the post-save auth-health probe before forcing a failure in the seeded-failure tests, eliminating a goroutine race.
- Reorder authMethod precedence in setJiraConfig/setLinearConfig to put the spread first so 'caller wins' reads naturally.
