6082e59d47 fix(eventstore): allow overwriting resource owner of events (#12261)
# Which Problems Are Solved

- The eventstore did not support intentionally overwriting the resource
owner when creating events for aggregates that may be reused across
owners.
- Resource owner handling was implicit and could not be controlled per
command/event type.
- We needed a safe way to distinguish between:
  - keeping the existing aggregate owner, and
  - explicitly setting a new owner for specific create-like events.

# How the Problems Are Solved

- Introduced a new eventstore command type with an explicit
enforce_owner flag.
- Updated eventstore.commands_to_events and eventstore.push so owner
assignment is now explicit:
  - if enforce_owner is true, the command owner is written
- if enforce_owner is false, the existing aggregate owner is retained
when present
- Added EnforceResourceOwnerCommand and wiring so command types can opt
in to enforced owner behavior.
- Wired the new behavior through the v3 eventstore push path, including
compatibility fallback for older command type mapping.
- Added migration/setup changes to register and use the new command type
and SQL functions.
- Added and updated tests for owner overwrite and aggregate ID reuse
scenarios.

# Additional Changes

- Added small migration/setup robustness improvements related to
eventstore setup ordering and helper reuse.
- Added focused test coverage for enforced owner behavior and
sequencing.
- Events that currently allow owner changes (implement
EnforceResourceOwner) are:
  - AddedEvent (action)
  - GroupAddedEvent
  - StartedEvent (idp intent)
  - ProjectAddedEvent
  - HumanAddedEvent
  - HumanRegisteredEvent
  - MachineAddedEvent
  - CreatedEvent (schema user)

# Additional Context

- Follow-up for eventstore owner-handling correctness in create flows
and aggregate ID reuse cases.
- No additional issue link was attached for this change.
