2277cbd7e2 fix(ugc): stopping the UGC server cancels the models being made
Stopping waited for every worker to finish its model, and with the path
traced hidden-face removal a big model takes minutes, so a restart hung.
UgcThrottle::Cancel(true) (set by UgcProcessor::Stop) makes Checkpoint,
which the long loops already call, throw UgcThrottle::Cancelled; the worker
abandons the job without writing or recording anything, so its row stays
waiting and is made again after the restart. The throttle's sleeps wake to
check it. Previews answer 503.

7c5d69c1ed feat(ugc): make models like LU Toolbox does, within CPU and memory budgets
Parity with LU Toolbox's Process Model, Bake Lighting and icon renderer, with
its defaults as the settings' defaults:

- Colors from its LU palette (UgcPalette: LU colors, LDD colors mapped to the
  nearest LU one, unknown ones black), transparent bricks at 58.82% opacity, a
  brick transparent only when all of its materials are.
- Color variation: each brick's material gets its HSV value shifted in a 2.224
  gamma by up to 5% (times the color's own amount), from a random number of
  the model, brick and material, so reprocessing gives the same colors in
  every LOD. Icons get none, and the icon renderer's color corrections.
- LODs 0 and 2 with its distance logic, written as NiLODNode/NiRangeLODData
  like its exports and the game's own brick models, shapes divided at 65535
  vertices along the longest side like divide_mesh.
- Ambient occlusion like its AO-only bake: 64 rays per vertex, distance 5,
  after hidden surface removal, transparent bricks neither baked nor
  occluding, glow colors added.
- Icons from its icon scene: 50 mm lens at 53.4/19.5 degrees, sun of 2.5 at
  21/50.3 degrees with soft shadows, grey world light with occlusion; LOD 0's
  hidden surface removal and occlusion are reused for them.
- Optional ground plane for hidden surface removal; stats.json per model and
  the previous version's previews kept for comparing.

Budgets, applied live on config reload: max_cpu_percent (workers account
their thread CPU time and sleep to stay under it, long renders included),
worker_nice, max_memory_mb (jobs are estimated from their brick count and
wait until they fit), max_model_bricks and pause_hours. /status and the
traffic report show CPU, memory and throttling.
