fix(security): suppress Allow-Credentials on wildcard CORS origin (CORS-1)
Per CORS spec §3.2, Access-Control-Allow-Credentials must not be
"true" when Access-Control-Allow-Origin is the wildcard "*".
ACHeadersMiddleware (pkg/common/http_server.go) and
getUIHeadersHandler (pkg/api/routes.go) now only emit the
credentials header when an explicit, non-empty AllowOrigin is
configured. Deployments that leave AllowOrigin blank (default
wildcard) no longer produce a contradictory header pair.

Wrap req.Body with http.MaxBytesReader before io.ReadAll in
CreateAPIKey. Requests with bodies larger than MaxAPIKeyBodySize
(4 KiB) now return HTTP 413 instead of buffering arbitrary data.
Add the MaxAPIKeyBodySize constant, update the Swagger @Failure
annotation to document 413, and add a unit test.

Wrap request.Body with http.MaxBytesReader before io.ReadAll in
UpdateManifest. Bodies exceeding MaxManifestBodySize (4 MiB) now

Add the MaxManifestBodySize constant and a unit test that sends an
oversized body and asserts the 413 status.

Adds a configurable maximum repository count per registry instance.
When maxRepos is set on StorageConfig, manifest pushes that would create
a new repository beyond the limit are rejected with HTTP 429
TOOMANYREQUESTS. Pushes to existing repositories are always allowed.
Implemented as an always-available feature in pkg/api (not a build-tag
extension). MaxRepos is a field on StorageConfig, enabled when > 0.
- repoQuotaMiddleware on the dist-spec router intercepts manifest PUTs.
New-repo pushes are serialized with a sync.Mutex to prevent concurrent
requests from exceeding the limit.
- Adds CountRepos(ctx) to the MetaDB interface with efficient
implementations: BoltDB (Stats().KeyN), Redis (HLen), DynamoDB
(Scan with Select=COUNT).
- Config.IsQuotaEnabled() added, wired into controller.go metaDB init.
- Four integration tests (enforcement, concurrency, disabled,
unconfigured) and backend-specific CountRepos tests for BoltDB, Redis,
and DynamoDB.

* fix: make config read/write thread safe and fix some other similar issues
1. The config config has a lock, and safe methods to update and read the attributes
2. The config has methods to retrieve copies of specific attributes, such as the extyensions config, the auth config, and the authz config.
These are needed, as the config object may mutate in the middle of an auth/authz requests, and we avoid partial configuration being applied for that request.
3. Fix an issue with the monitoring server not stopping when the controller is shut down.
4. Fix an issue with the HTPasswdWatcher not stopping when the background tasks are supposed to finish.
5. Fix some tests using hardcoded ports.
Moved some of the methods which were on the main config to the auth, access control and extension configs

* fix: migrate to Go module v2 for proper semantic versioning
This change updates the module path from 'zotregistry.dev/zot' to
'zotregistry.dev/zot/v2' to comply with Go's semantic versioning rules.
According to Go's module versioning requirements, major version v2+
must include the major version in the module path. The current
module path 'zotregistry.dev/zot' only supports v0.x.x and v1.x.x
versions, making existing v2.x.x tags (like v2.1.8) unusable.
Changes:
- Updated go.mod module path to zotregistry.dev/zot/v2
- Updated all internal import paths across 280+ Go source files
- Updated configuration files (golangcilint.yaml, gqlgen.yml)
- Updated README.md Go reference badge
This fix enables proper use of existing v2.x.x Git tags and allows
external packages to import zot v2+ versions without compatibility
errors.
Resolves: Go module import compatibility for v2+ versions
Fixes: #3071

A new config section under "HTTP" called "Compat" is added which
currently takes a list of possible compatible legacy media-types.

Only "docker2s2" (Docker Manifest V2 Schema V2) is currently supported.

when a client pushes an image zot's inline dedupe
will try to find the blob path corresponding with the blob digest
that it's currently pushed and if it's found in the cache
then zot will make a symbolic link to that cache entry and report
to the client that the blob already exists on the location.
Before this patch authorization was not applied on this process meaning
that a user could copy blobs without having permissions on the source repo.
Added a rule which says that the client should have read permissions on the source repo
before deduping, otherwise just Stat() the blob and return the corresponding status code.

* feat(cluster): support shared storage scale out
This change introduces support for shared storage backed
zot cluster scale out.
New feature
Multiple stateless zot instances can run using the same shared
storage backend where each instance looks at a specific set
of repositories based on a siphash of the repository name to improve
scale as the load is distributed across multiple instances.
For a given config, there will only be one instance that can perform
dist-spec read/write on a given repository.
What's changed?
- introduced a transparent request proxy for dist-spec endpoints based on
siphash of repository name.
- new config for scale out cluster that specifies list of
cluster members.

1. Move existing CVE DB download generator/task login under the cve package
2. Add a new CVE scanner task generator and task type to run in the background, as well as tests for it
3. Move the CVE cache in its own package
4. Add a CVE scanner methods to check if an entry is present in the cache, and to retreive the results
5. Modify the FilterTags MetaDB method to not exit on first error
This is needed in order to pass all tags to the generator,
instead of the generator stopping at the first set of invalid data
6. Integrate the new scanning task generator with the existing zot code.
7. Fix an issue where the CVE scan results for multiarch images was not cached
8. Rewrite some of the older CVE tests to use the new image-utils test package
9. Use the CVE scanner as attribute of the controller instead of CveInfo.
Remove functionality of CVE DB update from CveInfo, it is now responsible,
as the name states, only for providing CVE information.
10. The logic to get maximum severity and cve count for image sumaries now uses only the scanner cache.
11. Removed the GetCVESummaryForImage method from CveInfo as it was only used in tests
