Completes 22ece5199 (open 5.0 dev line): root is 5.0.x-dev but the
self-referential api-platform/* constraints were left at ^4.4@alpha,
which is unresolvable in the component split-tests (published 4.4
alphas require metadata ^4.4, conflicting with the 5.0 root).

Symfony 7.4 is the new LTS; bump every symfony/* floor to ^7.4 (|| ^8.0)
across all components and drop 6.4 / 7.0-7.3 support. Also bump the
extra.symfony.require declaration in each composer.json to ^7.4 || ^8.0
to stay consistent with the new floor (read by flex in CI).

Cleanups the floor unblocks:

• ParameterValidatorProvider: drop the getConstraint()/getCause()
  method_exists shims (guaranteed on ConstraintViolationInterface >= 7.2)
• OperationRequestInitiatorTrait: drop a stale TODO

#7115 added cross-package calls new in 4.4 — getStateOptionsRepositoryMethod()
in api-platform/state and the repositoryMethod constructor argument in
api-platform/doctrine-common — that 4.4 provider code invokes. The old
^4.2/^4.3 sibling floors let composer update --prefer-lowest pull releases
lacking these symbols, so the per-component lowest CI jobs failed with
"undefined method" / "unknown named parameter".

Floor all api-platform/* inter-package constraints at ^4.4. The @Alpha
stability flag is required because the subpackages set minimum-stability:beta,
under which a plain ^4.4 would not match the 4.4.0-alpha prereleases. Revert
to plain ^4.4 once 4.4.0 stable ships.
