e2e: scope the FrankBook-Pro leg to its own trigger-gated Playwright project

The 11-admin spec walked links that terminate on FrankBook-Pro
(192.168.0.112), which sleeps when idle — every deploy gate timed out
there (measured 2026-10-05, two deploy windows). Split: the frankbook
links move to tests/e2e/specs/19-frankbook.spec.ts under a frankbook
project that run.sh excludes by default and deploy.sh triggers ONLY
when a frankbook blast-radius path changed (the spec, frankbook-pro/,
the homepage registry, the Caddyfile arr vhosts). deploy.sh computes
the trigger from the same BASE..HEAD revision range the plan uses.
