Two harness defects, both of which silently destroyed coverage rather than
reporting anything useful:
* conftest's session `event_loop` fixture called asyncio.get_event_loop() with
no running loop. That is deprecated on 3.12 and raises on 3.14, and because
it is a fixture every async test errored at setup: a full run reported 1151
errors and 0 passes in 10s, which reads like a catastrophic browser failure
and is not. Allocate and install a fresh loop instead.
* async/test_page_route.py imported playwright._impl._glob.glob_to_regex, which
Playwright renamed to glob_to_regex_pattern (now returning the pattern string
rather than a compiled regex). A module-level ImportError dropped all 43
route tests from collection -- the tests covering exactly the code path the
routed-header fix touches. Shim it, keeping the old helper's semantics.
Collection goes from 1182 tests + 1 error to 1225 tests, and the suite runs
under both 3.12 and 3.14.
