Both are pluggable seams (dev-plan-4.md §1.2 items 1-2), same shape as
T20's sendVerificationEmail: a fixed env var gates a real vendor call
that isn't implemented yet (none has been picked), and the no-vendor
path is what actually runs today.

describeGarmentImage() — mode 2 has no admin around to hand-write
garments.appearanceDescriptor the way admin_seed garments do, so it
needs *something* non-empty to fill that field; today that's a fixed
placeholder string, swapped for a real vision-model call once a
vendor's picked.

moderateGarmentImage() — the requirements doc flags image-content
moderation as vendor-TBD but never actually lists it as its own task;
this fills that gap. Every call writes a moderation_log row (new
dressup-store.js export, M.9 schema) regardless of which branch runs,
so the audit trail exists before a real vendor does. Default-permissive
when unconfigured — T2's upload endpoint already enforces the real
trust-boundary checks (magic-byte type check, 8MB cap, EXIF-stripped
re-encode); this only covers the *content* check, which nothing here
can perform without a vendor.

Neither is unit-tested standalone (server.js doesn't export internal
functions, matching sendVerificationEmail's existing precedent) — T27
integration-tests both through the actual upload endpoint.

Also adds pricing.js to the tmpdir file-copy list in every test that
spawns server.js in isolation — server.js now requires it.

generateDanceVideo() takes a queued generationJobs record through
prompt build -> forward character/garment/dance-ref uploads to H3
Console's /v1/assets -> POST /v1/videos -> poll -> push a traced clip
into library.json (characterId/garmentId/refDanceVideoId). Mirrors
generateForPrompt's submit/poll/persist shape but keyed off the new
generationJobs store so a restart resumes any in-flight job by its
h3JobId, same as resumeGenerations() does for the live queue.

POST /api/admin/generate accepts characterId/garmentId (+ optional
refDanceVideoId, else a random active dance-ref is picked) and skips
straight to the cached clip if that character x garment combo was
already generated (M.7 dedupe). GET /api/admin/generate/:id polls job
status.

Tests spin up a mock H3 Console over HTTP so the full submit/poll/land
path runs offline. Also fixes two existing test fixtures
(dressup-crud, admin-pages-flow) that spawn server.js without copying
prompt-template.js — worked until T8 added the first require() of it
into server.js, at which point the spawned server silently failed to
boot.

Generic createStore(filePath) shared by characters.json/garments.json/
dance-refs.json, same full-read/full-write pattern as library.json.
Not yet wired into server.js routes — that's T3-T5.
