Linked issue: IT-1112: Per-author tracked change colors

Status	Acceptance criteria	Notes
✅	Expose host config modules.trackChanges.authorColors (enabled/overrides/resolve) so hosts can specify per-author colors	Config shape added across public types/docs and composeAuthorColorResolver re-exported for SuperDoc to build the resolver from host config.
✅	Compose a resolver honoring overrides (email first, then name), optional resolve callback, and a deterministic fallback color	composeAuthorColorResolver implements overrides → resolve → fallback order; fallbackAuthorColor provides deterministic palette; tests cover override lookup, fallback stability, and host-resolver exceptions.
✅	Stamp a paint-ready color (TrackedChangeMeta.color) on every tracked-change layer during adapter conversion so the painter need not call host callbacks	stampTrackedChangeColors is implemented and invoked in the pm-adapter before paint, stamping or clearing meta.color based on the resolver.
✅	Painter applies per-author CSS variable families (--sd-tracked-changes-*) for insert/delete/format layers and derives translucent backgrounds from the base color	Dom painter applies CSS variables from meta.color per layer kind and derives alpha variants; tests assert the variables are set.
✅	UI snapshot exposes per-item authorColor and an ordered authors list with resolved colors so review UIs can render a legend consistent with painted colors	createSuperDocUI composes the resolver, populates items with authorColor and an authors list, types and tests were updated to expect these fields.
✅	Disabling or omitting the feature clears stale colors from cached blocks and leaves default palette behavior intact	stampTrackedChangeColors accepts undefined to clear colors; composeAuthorColorResolver returns undefined when config disabled, and adapter only stamps when resolver provided.
