feat(meta): add TaggedTimestamp field and preserve during re-parsing
Add TaggedTimestamp field to track when image tags were created, exposed
through GraphQL API. Previously, when zot restarted and re-parsed storage,
ResetRepoReferences would clear all tags, causing timestamp information to
be lost and reset to the service restart time for existing images.
This change adds TaggedTimestamp support and modifies ResetRepoReferences to
selectively preserve tags that still exist in storage, maintaining their
TaggedTimestamp values. Tags that no longer exist in storage are removed as
before.
Changes:
- Add TaggedTimestamp field to GraphQL ImageSummary schema
- Update GraphQL conversion functions to populate TaggedTimestamp with
fallback to PushTimestamp when unavailable
- Updated ResetRepoReferences interface to accept tagsToKeep parameter
- Modified ParseRepo to collect tags from storage before resetting
- Updated all backend implementations (Redis, DynamoDB, BoltDB) to preserve
tags in tagsToKeep instead of clearing all tags
- Updated tests and mocks to match new signature
This ensures TaggedTimestamp accurately reflects when tags were originally
created, and exposes this information through the GraphQL API.

in the case of an already existing meta db without pushTimestamp field
its value would be 0 until image is updated, check for zero values and update them
with time.Now() so that retention logic won't remove them.
