Lazy-load plugin registries, move DB sync to dispatcher (#16483)

Browse Source 
Move plugin loading to lazy-on-first-access, DB sync to dispatcher

Remove credential type and inventory plugin loading from Django's
app.ready() path. In-memory registries (ManagedCredentialType.registry
and InventorySourceOptions.injectors) are now populated lazily on first
access via LazyLoadDict, a dict subclass that calls a loader function
on the first read operation. This ensures web workers, dispatcher
workers, and management commands all get the registries populated
exactly when needed, without eager loading at startup.

The DB sync (CredentialType.setup_tower_managed_defaults) is moved to
the dispatcher's startup task, where it only needs to run once per
deployment rather than in every Django process.
