[🔗](https://github.com/mishka-group/mishka_document/blob/v0.0.1/lib/mishka_document/resources/__helpers/advisory_lock_key_generator.ex#L5)

Extends AshEvents default advisory lock key generator to support nil tenants.

This is needed for master admin actions that bypass multi-tenancy (nil tenant).
For non-nil tenants, delegates to the default AshEvents implementation.
