* fix(storage): resolve double-prefixing issue for GCS rootdirectory
Preserve double-prefixing for S3 to maintain backward compatibility with existing data. For GCS, always use "/" as rootDir to avoid double-prefixing, as GCS rootdirectory usage is a newer feature without legacy data.

Require blob files to follow standard OCI image layout:
rootDir/repo/blobs/algorithm/digest
- Validate grandparent directory is ImageBlobsDir
- Validate parent directory is valid digest algorithm
- Update tests to use standard OCI structure
- Add blobPath() helper to reduce duplication and fix linting
This should reduce the number of uneeded digest computations
if other non-oci specific files are present in the layout.
Fix also a race condition when picking ports in monitoring tests.

* 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

Using just the last repository is not enough as in the case when it is deleted
(either by GC or some other way), GetNextRepository returns empty string
causing the generator to be marked completed without any errors.
An alternative would have been to start over from the first repository,
but this can take hours if multiple repositories need to be deleted,
not to mention the processing power and I/O and S3 load this could take.

Issue #724
A new config section under "HTTP" called "Compat" is added which
currently takes a list of possible compatible legacy media-types.
https://github.com/opencontainers/image-spec/blob/main/media-types.md#compatibility-matrix
Only "docker2s2" (Docker Manifest V2 Schema V2) is currently supported.
Garbage collection also needs to be made aware of non-OCI compatible
layer types.

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.
