* feat(storage): add a common blobstore to store all blobs (#3906)
Currently, zot uses one of the existing repos as the master copy for a blob to
achieve dedupe, which complicates dedupe tracking logic. Furthermore, we
have a global storage lock which is becoming a bottleneck. In order to
move to a per-repo lock, we first need to simplify this logic.
Now use a single hidden global repo (_blobstore/) as a blob store instead.

* refactor(test/blackbox): extract shared push/pull helpers
Move duplicated push/pull/regclient/oras/helm helper functions out of
fips140.bats, pushpull.bats and helpers_upgrade.bash into a single
helpers_pushpull.bash, then have all three suites load from there.
The helpers now share verify_prerequisites, get_zot_port, common assertion
helpers (catalog/tag presence, OCI index ref name) and the regclient
pagination listing. helpers_upgrade.bash keeps only the test_release_*
and test_new_* wrappers that compose those helpers.
Net effect: ~1000 lines of duplicated test scaffolding removed across
the four files; behavior of the existing test cases is preserved.

* refactor(test/blackbox): share pushpull lifecycle and dedupe authn helpers
Build on the shared helpers_pushpull.bash to remove more duplicated
blackbox scaffolding:
- Add pushpull_setup_file/pushpull_teardown/pushpull_teardown_file keyed
on PUSHPULL_FIPS_MODE so pushpull.bats and fips140.bats only set the
flag and delegate lifecycle, instead of each carrying a near-identical
setup_file/teardown.
- Add helpers_pushpull_authn.bash (loaded by pushpull_authn.bats and
fips140_authn.bats) for shared htpasswd setup, FIPS vs non-FIPS config
and teardown, and the regclient/OCI/ML test helpers; both authn suites
collapse to one-line @test bodies keyed on PUSHPULL_AUTHN_FIPS_MODE.
- Make each authn helper self-sufficient by performing its own regctl
login, removing the hidden dependency on the first test having logged
in.
- Split the implicit manifest delete out of helper_pull_image_index_and_delete
into a standalone helper_delete_manifest, surfaced as its own
"delete image index" @test in the pushpull, fips140 and upgrade suites,
so the delete is explicit and no longer an order-fragile side effect of
a pull.

* fix(test/blackbox): harden flaky oras pull and sync signature tests

Use curl --fail for manifest deletes so HTTP errors fail the test. Remove

* fix(test/blackbox): isolate regctl config per BATS suite
regctl persists login and TLS settings on disk, so push/pull blackbox
tests could leak state into ~/.regctl/config.json across suites. Point
REGCTL_CONFIG at BATS_FILE_TMPDIR for pushpull, authn, and upgrade
suites, configure TLS once in authn setup, and drop redundant logout
and per-login TLS setup.

* fix(test/blackbox): harden upgrade suite log dump on failure
Touch zot-log.json during upgrade setup and only cat it in teardown when
the file exists, so a missing log cannot mask the underlying test failure.

Changes in this PR
==================
- Replaces the get_free_port bash function in BATS tests
with get_free_port_for_service that returns a random free port
in a given range for a test file and service defined in a
ports.json file.
- Updates all get_free_port calls to use the new function.
- A new README file for details on the ports.json file.
- Updates some tests using fixed ports to use dynamic ports.
- Adds a ports.json file with all the allocations.
- Adds a new common helper for port fetching.

New examples of running tests:
1. To run a specific bats file (with and without verbose output):
make run-blackbox-tests BATS_TEST_FILE_PATH=test/blackbox/delete_images.bats
make run-blackbox-tests BATS_TEST_FILE_PATH=test/blackbox/delete_images.bats BATS_VERBOSITY=2
2. To run the CI tests (with and without verbose output)
make run-blackbox-ci
make run-blackbox-ci BATS_VERBOSITY=2
BATS_TEST_FILE_PATH is used to pass on the test file to run using `run-blackbox-tests`
BATS_VERBOSITY controls the verbosity of the bats framework output, if unspecified the output only
contains test results and failure message in case of failures.
If BATS_VERBOSITY is 1, then also show commands as they are executed.
If BATS_VERBOSITY is 2, on top of the above it also shows output of passed tests.
Other changes in this PR:
- Update some of the tests to show logs after the run ends.
- Run the linters before the tests, as it saves time on failures when running in GH

before syncing an image we first check if it's already present in our storage
to do that we get the manifest from remote and compare it with the local one
but in the case of syncing docker images, because the conversion to OCI format is done while
syncing, we get a docker manifest before conversion, so sync detects that local manifest and
remote one are different, so it starts syncing again.
to overcome this, convert remote docker manifests to OCI manifests and then compare.
