test(ci): OS-assigned ephemeral ports for subprocess suites — kill the port-collision flake (#176)
The subprocess-booting test suites hand-picked fixed ports in a cramped ~3955-4021 range, and
156-schedule-read-path deviated to a RANDOM port (3900 + rand%90) that overlapped those fixed
ports. Under CI load two servers could race on the same port, surfacing as flaky "no such table:
devices" / "FOREIGN KEY constraint failed" (a server answering a request against a half-migrated
or wrong DB). It's environmental — the suites pass locally and in isolation.

Fix: a shared test/helpers/free-port.js (bind :0 on loopback, read the OS-assigned port, release)
called in before() so every suite gets a guaranteed-unique ephemeral port — concurrent suites can
no longer collide, and no one has to hand-assign ports.

- Codemod converted 30 suites: const PORT = <fixed|random> -> let PORT (+ BASE) assigned via
  `PORT = await freePort()` at the top of before().
- 3 hand-fixed (different structure): 148-eviction-storm (lowercase `base`), boot-health (no
  before() — allocates PORT + a throwaway SEED_PORT inside the test, replacing the hardcoded
  3894), totp-keyrotation (no before() — allocates at the test start before bootServer()).

No fixed 39xx/40xx ports remain. Full server suite 435/435; the 4 hand-touched suites pass in
isolation. Pure test-infra change — no app code touched.
