fix: misc fixes

[nikophil]

here are some easy fixes from the list here

expect some more in the coming days 😅

I really fixed the easiest stuff here:

---

This one fixes a major failure I have in my app:

• [x] we should catch both "persistence" and ORM/ODM MappingException used here and here is sometimes

---

This was one of my main problem: we need to disable autorefresh when using flush_after()

• [x] flush_after() throws the following error:

  Cannot auto refresh "App\Domain\Program" as there are unsaved changes. Be sure to call ->_save() or disable auto refreshing

---

This is a BC break, we can mitigate easily here. Moreover I think is is legit tu allow to ask "from 0 to x items"

• [x] randomRange() does not accept 0 anymore

---

Following ones are easy picks:

• [x] we should not forget to add an empty Factory::__construct()
• [x] we should add @mixin T in Proxy other wise there will be sca problems in the rare places where Proxy is still type-hinted
• [x] object should be saved again after afterPersist callbacks
• [x] proxy_factory() missing

I don't know your feelings toward this: should we still support Symfony 5.4 (still supported till late 2024)? and thus support php 8.0?

I'd like foundry 2.0 to be 6.4+ so PHP 8.1+
