Handle wildcard proxy hosts and stabilize test coverage

- accept wildcard proxy host domains like *.example.com with validation and normalization
- make exact hosts win over overlapping wildcards in generated routes and TLS policies
- add unit coverage for host-pattern priority and wildcard domain handling
- add a single test:all entry point and clean up lint/typecheck issues so the suite runs cleanly
- run mobile layout Playwright checks under both chromium and mobile-iphone
