fix(sync): use GlobalComponentRegistry for network sync decoding (#392)

- Decoder.ts now uses GlobalComponentRegistry.getComponentType() instead of local registry
- @sync decorator uses getComponentTypeName() to get @ECSComponent decorator name
- @ECSComponent decorator updates SYNC_METADATA.typeId when defined
- Removed deprecated registerSyncComponent/autoRegisterSyncComponent functions
- Updated ComponentSync.ts in network package to use GlobalComponentRegistry
- Updated tests to use correct @ECSComponent type names

This ensures that components decorated with @ECSComponent are automatically
available for network sync decoding without any manual registration.
