Fix e2e tests: update for route-default tab, add hydration and calendar tests

- Fix 5 pre-existing failures: default tab is 'route' not 'flight'
- Add test: route search results page hydrates filter from URL params
- Add test (skip): route search form end-to-end (needs live API)
- Add test (skip): calendar strip shows day numbers (needs live API)
- Mark feedback button test as fixme (component not wired in)
