fix: multiple fixes based on recent test failures (#3582)

* fix(monitoring): fix race condition in TestPopulateStorageMetrics

Write images to filesystem before starting controller to prevent GC
from reading index.json while it's being written.

See failure:

* fix(sync): fix TestSignatures assertion on referrers order

Search through all referrers to find the expected OCI ref digest instead
of assuming it's at index.Manifests[1], as the order is not guaranteed.

See https://github.com/project-zot/zot/actions/runs/19630382617/job/56208492397?pr=3579

* fix(redis): fix error handling in GetMultipleRepoMeta

The function was returning err at the end, which could be nil even when
HGetAll should have failed, because err gets reassigned in the loop.
Changed to return nil on success path, ensuring HGetAll errors are
properly propagated. Fixes TestRedisUnreachable failure.

See https://github.com/project-zot/zot/actions/runs/19634990856/job/56223414955?pr=3582

* refactor(sync): simplify sync test structure and restore file permissions

Remove unnecessary nested Convey blocks and integrate error tests into
parent blocks. Add defer statements to restore file permissions after
chmod operations to prevent side effects on subsequent tests.

Fix potential root cause of https://github.com/project-zot/zot/actions/runs/19636284485/job/56227682319?pr=3579
