This fix prevent repetition children types de champ from being pulled from cloned procedures. stable_id is stable across revisions but also across cloned procedures.
Before, every time a password was tested, the dictionaries were parsed
again by zxcvbn.
Parsing dictionaries is slow: it may take up to ~1s. This doesn't matter
that much in production, but it makes tests very slow (because we tend
to create a lot of User records).
With this changes, the initializer tester is shared between calls, class
instances and threads. It is lazily loaded on first use, in order not to
slow down the application boot sequence.
This uses ~20 Mo of memory (only once for all threads), but makes tests
more that twice faster.
For instance, model tests go from **8m 21s** to **3m 26s**.
NB:
An additionnal optimization could be to preload the tester on
boot, before workers are forked, to take advantage of Puma copy-on-write
mechanism. In this way all forked workers would use the same cached
instance.
But:
- We're not actually sure this would work properly. What if Ruby updates
an interval ivar on the class, and this forces the OS to copy the
whole data structure in each fork?
- Puma phased restarts are not compatible with copy-on-write anyway.
So we're avoiding this optimisation for now, and take the extra 20 Mo
per worker.
Use of one-dimension arrays comparison & `contain_exactly` RSpec matcher
to avoid this behaviour:

Follow-up of #5953.
Refactor the concerns with two goals:
- Getting closer from the way ActiveStorage adds its own hooks.
Usually ActiveStorage does this using an `Attachment#after_create`
hook, which then delegates to the blob to enqueue the job.
- Enqueuing each job only once. By hooking on `Attachment#after_create`,
we guarantee each job will be added only once.
We then let the jobs themselves check if they are relevant or not, and
retry or discard themselves if necessary.
We also need to update the tests a bit, because Rails'
`perform_enqueued_jobs(&block)` test helper doesn't honor the `retry_on`
clause of jobs. Instead it forwards the exception to the caller – which
makes the test fail.
Instead we use the inline version of `perform_enqueued_jobs()`, without
a block, which properly ignores errors catched by retry_on.
