Local database maintenance actions require local chunk revisions and fully replicated chunks, but previously failed with a notice when those settings were not already configured.
This adds a small prerequisite confirmation helper for the maintenance commands. When required settings are missing, the user can apply them and continue from the action they already started, or cancel without changing settings.
Covers both required maintenance settings:
- Compute revisions for chunks enabled
- Fetch chunks on demand disabled
