Enable Container Registry DB backups for Registry GA
## Short description <!-- add a short summary of what is being proposed --> The container registry meta db is not currently being considered for backup using the current backup and restore rake tasks https://gitlab.com/gitlab-org/gitlab/-/issues/532507 This feature is [committed to be GA by Q4](https://gitlab.com/gitlab-org/gitlab/-/issues/532507#note_2511480980) so we need to create a backup and restore solution for customers. ## Connection to technical roadmap <!-- Link to https://infra-roadmap-c6d14f.gitlab.io/ items, such as https://infra-roadmap-c6d14f.gitlab.io/#project-durability_unified_backup_restore In the technical roadmap [YAML](https://gitlab.com/gitlab-com/gl-infra/infra-roadmap/-/blob/main/data/stage-data_access.yml), explain how the project aligns with stated goals of the company.

How will it be measured? --> - Meet customer requirements for backup and restore that includes the Registry meta db. ## Exit criteria <!-- When is it done? Prevent scope creep by defining it here! --> 1. We can backup and restore the container registry db in both Omnibus and CNG environments 1. Registry meta-database is part of our automated backup and restore testing ## Participants @ibaum @vespian_gl ## Timeline and Effort <!-- How much time do we think it'll take to complete? Wild guesses are appropriate here! We can always iterate on any section here. --> <!-- DO NOT EDIT BELOW - Used for the epic status automation bot --> <!-- STATUS NOTE START --> ## Status 2026-04-16 This was the final week for the project.
