Catalog: eleven tests leave for their host proofs

Each left after its host cases passed (forgectrl 1dc85f6) and with
the coverage lint clean at the pins, its only failure the known
setup.check-lens entry on src/lensfind.*:

- forgectrl.tokens: host_routes.sh's scoped tokens (a route refused to a
  token not given it, neither token in the list or the store), with
  tokens_test and auth_scoped_test.
- update.product-gate: host_update.sh's product gate on the upload, with
  fwproduct_test.
- setup.first-run-page: tests/wizard_walk.py.
- setup.check-sensors, setup.check-intakes, setup.check-cameras,
  setup.check-flow-verify, setup.check-envelope, setup.floor:
  host_setup.sh's checks and the floor burn, with wizcalc_test.
  envelope_test.py's cases are unchanged. setup.floor's emission stays
  with setup.focus and laser.emission-witness.
- motion.job: jobpost_test, with jobrun_test and lease_test; jobpost.* is
  covered by exthost.motion-job, which stays.
- exthost.motion-jog: host_routes.sh's credential case.

Two HOST_TESTED rows, each a binary forgectrl's build.yml runs at the pin
c274f19 that proves the path the lint named: src/fwproduct.* to
fwproduct_test, src/grblport.* to grblport_test.

exthost.motion-job now requires motion.jog-roundtrip in place of
motion.job. bedsize.py held setup.check-envelope alone and goes;
forgectrl.py loses _words_of and its hw import, motion.py the job
runner's helpers, setup_burns.py FLOOR_KEY and FLOOR_KEYS.

forgetest's own tests: test_setup_dark.py loses the sensors and intakes
judges and the departed ids; test_setup_burns.py loses the floor's cases,
and the guards burn() and preview_ok() hold for the focus burn (the
program's tail and reach, the thickness in inches and the one refused, a
prompt not answered, the witnesses) run on setup.focus.

Stay: forgectrl.auth (the fuse view's button refusal on the real
button); forgectrl.settings-bounds (the lid lamp: cam.c writes
/sys/glowforge/pic/lid_led, not under GF_SYSFS_ROOT); forgectrl.panel-serves
(src/ui.h, which no binary at the pin proves; Z inside the lens reach is
setup.check-lens's); logs.routing; setup.account-login (the account's
render and its home, image content); setup.ssh-until-reboot
(src/paths.h); setup.machine-name (udhcpc -x hostname and no mDNS
responder, image content); setup.first-run-flow (src/button.*, led.*,
advisories.*, hooks.h and the four advisory documents); exthost.motion-job
(jobpost.*, which no binary at the pin proves).

Proof: the coverage lint, 55 tests; pyflakes; test_setup_burns,
test_setup_dark, test_takeover_position and test_image (54 OK).

Shared text moved the fingerprints of exthost.armed-freeze,
exthost.platform, exthost.service, forgectrl.auth,
forgectrl.panel-serves, forgectrl.settings-bounds, laser.armed-kill,
laser.emission-witness, laser.pause-resume-lid-cancel,
motion.cancel-abort, motion.deadman, motion.jog-roundtrip,
motion.liveness-probe, motion.microstep-modes, motion.pacing,
motion.release, motion.step-timing-under-load, setup.account-login,
setup.check-airflow, setup.check-lens, setup.check-motion,
setup.check-switches, setup.cloud-header-capture, setup.first-run-flow,
setup.focus, setup.machine-name, setup.ssh-until-reboot and
update.slots-and-signature; exthost.motion-job's own text moved with its
requires.
