fix(test-e2e-playwright): scale onion timeouts by the tor flavor instead of a flat five

resolveTimeout multiplies every Playwright window by 5 for a .onion
target. That default arrived in 35dee215c8 (2026-07-08), before
5399b48482 (2026-07-24) gave CI the chutney flavor, a private Tor net on
localhost, and PLAYWRIGHT_ONION_TIMEOUT_MULTIPLIER was never set. Waits
that expire by design therefore cost five times their base under chutney
too, which is where most of the Tor surcharge came from.

The Playwright run now passes the multiplier for onion targets only,
looked up from svc-net-tor's services.tor.flavor: 2 for chutney, 5 for
the public network, whose circuits really are slow. An unknown flavor
fails the lookup instead of falling back, and a unit test holds every
flavor directory of svc-net-tor to an entry.

Chutney traces of run 34421944328: 700 successful timed waits across 186
tests used at most 0.42 of their unscaled window, and the longest
client-side expect took 5.1s. Across runs 34421944328 and 34419507038 no
chutney test with its own ceiling (401 of them) used more than 53% of
the new x2 ceiling, even at today's x5-stretched duration.
