During the L2 bridge test setup, a matrix
was previously used so the fixtures would
run twice: once with the Linux bridge and
once with the OVS bridge.
Since the use of a matrix is not explicit
and can be confusing, the tests now use
pytest.parametrize at the test class
level instead.

## Summary by CodeRabbit

* **Tests**
* Replaced Cirros-based test fixtures and data sources with Fedora-based
ones for storage clone scenarios.
* Added Fedora data sources for filesystem and block volume modes;
removed the corresponding Cirros fixtures.
  * Updated VM flavor and memory defaults to Fedora values.
* Adjusted clone test references and size/overhead calculations to use
Fedora images.

…ream (#4196)

##### Short description:
Changed instance_type_centos_os_list os_name changed from centos to
centos.stream

##### More details:
instance_type_centos_os_list os_name was incorrect as the data source
and preference name are centos-stream/centos.stream leading to failure
on VM creation in test_centos_os.py

##### What this PR does / why we need it:
Fix failing tests at
tests/infrastructure/instance_types/supported_os/test_centos_os.py

## Summary by CodeRabbit

* **Chores**
* Standardized CentOS naming in build/test matrices to "centos.stream"
and simplified architecture suffix handling so S390X no longer receives
special conditional treatment.

* **Tests**
* Updated unit tests to expect the "centos.stream" naming and the
revised arch-suffix behavior across affected matrix scenarios.

## Summary by CodeRabbit

* **Tests**
* Expanded L2 bridge tests to run against both Linux and OVS bridge
types and added a class-scoped fixture for selecting device type.

* **Refactor**
* Test fixtures and VM setup updated to propagate the chosen bridge
device type and include explicit DHCP interface configuration for more
consistent test provisioning.

Small follow-up requested change
https://github.com/RedHatQE/openshift-virtualization-tests/pull/3588/changes#r2753623060

Use the allowed ports provided by the fixtures in network policy object
instead of the ports constant to improve test readability, and clearly
distinguish between allowed and disallowed ports.

## Summary by CodeRabbit

* **Tests**
* Updated network policy tests: renamed and reworked test fixtures and
signatures to remove redundant decorators, tests now consume targeted
fixtures and iterate over provided ports. This improves test clarity,
reduces duplication, and makes the network policy test suite more
reliable and easier to extend and maintain.
