fix(permissions): chunked synchronization of role permission events (#9403)

# Which Problems Are Solved

Setup fails to push all role permission events when running Zitadel with
CockroachDB. `TransactionRetryError`s were visible in logs which finally
times out the setup job with `timeout: context deadline exceeded`

# How the Problems Are Solved

As suggested in the [Cockroach documentation](timeout: context deadline
exceeded), _"break down larger transactions"_. The commands to be pushed
for the role permissions are chunked in 50 events per push. This
chunking is only done with CockroachDB.

# Additional Changes

- gci run fixed some unrelated imports
- access to `command.Commands` for the setup job, so we can reuse the
sync logic.

# Additional Context

Closes #9293
