Add appearance tint syncing (appearance v3)

Introduce tint syncing for skin/complection/makeup/beard by adding RemoteAppearanceTint and a tints vector, and bump appearance payload version to 3. Parse/emit tints in networking and update fake server/client test payloads. Capture live Player/NPC tintingData during appearance capture. Apply tints to proxies by updating existing entries or reconstructing missing ones via template resolution and MakeTintEntry (game allocator + vtable fixup); unresolved templates are skipped with throttled warnings. Update docs/changelog and add logging for applied tints. Backwards compatible with v1/v2 packets.

 apply only the parts they can resolve locally. Gender is intentionally not part
 of this payload yet; female proxy support can add it later.
