Inventory consumers of the current Nextcloud 35 image

[vitormattos]

Goal

Find and document every active consumer of the current Nextcloud 35 development image before that version-specific build is replaced.

This is part of #47.

Scope

Search LibreCode and LibreSign repositories for references to the current Nextcloud 35 image and its tag.

For each reference, record:

• repository and file;
• the image name and tag being used;
• whether the reference is active, obsolete, test-only, or documentation-only;
• whether the consumer will need a migration when the new generic master image is ready.

Do not update consumers in this issue.

Do not remove the current Nextcloud 35 image or workflow.

Expected result

Add a short inventory to this issue or to repository documentation that gives us a reliable migration checklist for the later cleanup task.

The inventory must be based on repository references, not assumptions.

Good first issue

This task is intentionally read-only. It prepares the safe removal of the version-specific image and should not change runtime behavior.
