Hide managed connectors until fully configured

A managed (Model B) connector like Crisp needs both the Probo-held key
and a resource ID (the plugin ID) to connect, but the driver catalog
gated visibility on the key alone. A deployment that set the key without
the plugin ID (reachable through raw JSON config; the bootstrap env path
already requires both) would show Crisp as connectable and then fail
every attempt with an internal error.

Add a RequiresManagedResourceID flag to the registration and a
Registry.ManagedConnectorReady check that requires both before a managed
provider enters the catalog, so a half-configured provider stays hidden
instead of dead-ending at connect.
