feat(ugc): icon light matched to the game, debounce, shared car icons, purge, icon editor

Brighter icons: a world light, a fill from the camera, a highlight, exposure
and contrast; with the defaults the icons' mean luminance matches the game's
own model icons (118 against 120 on a scratch set). Every icon parameter is
listed once (UgcIconParams: key, setting, range, default); the settings,
the dashboard's settings entries and the icon editor come from that list.
Presets per kind (player models, each car or rocket build type from
ModularBuildComponent) and overrides per model or module combination are in
ugc_icon_settings.

Saved models wait ugc_debounce_seconds (sharedconfig) after the owner's last
save before they're made (ugc.process_after); a client asking for one, the
owner leaving the world or a reset ends the wait.

Cars and rockets: one icon per combination of modules (sorted LOTs), shared
by every build of it; builds of a combination made already are marked made
right away, the client's per-blueprint downloads serve the shared files.

The dashboard can delete one item's files, purge by filter or all, preview
icons with any values on the UGC server (/admin routes, master password),
save presets and overrides, and draw a kind's icons again (icons only).

Migrations dlu/mysql/86 and dlu/sqlite/69. Not done yet: the dashboard
editor's lighting controls in the page script (routes are there), docs for
it, the empty-model state, /ugc?item= links, the shared fetch helper; the
storage size and property loading bugs are next.
