feat: add withoutDoctrineEvents() to suppress listeners during factory create

[seb-jean]

Motivation

When Foundry factories create entities during fixture loading, Doctrine event listeners attached to those entities fire as usual. This can cause unwanted side effects in tests — for example, sending emails, dispatching messages, or calling external services on every persist.

Related #216.

What this PR adds

A withoutDoctrineEvents() method on PersistentObjectFactory that temporarily removes Doctrine event listeners from the EventManager around the flush() call, then restores them immediately after.

API

// Disable ALL Doctrine event listeners during create()
PostFactory::new()->withoutDoctrineEvents()->create([...]);

// Disable specific listeners only
PostFactory::new()
    ->withoutDoctrineEvents(MyEventListener::class)
    ->create([...]);

I have 2 failing checks, but both are pre-existing issues unrelated to this PR.

fixes #957

hi @seb-jean

thanks to work on this! I have the need for this feature from time to time

Could you please add some more test cases:

• one using #[ORM\EntityListeners] on the entity
• one using #[AsEntityListener] on a listener
• one using flush_after() (I think you'll have to change some code to make it work)

Here are some questions, maybe for the future:

• is it possible to make it work with #[ORM\HasLifecycleCallbacks]?
• do you think it's possible to disable all listeners for a given event for an entity? meaning something like ->disableDoctrineEvents('prePersist')
