The page held one-off repairs from Nexus Dashboard (approve known pet
names, find/delete orphaned pet names, remove every buff, fix property
clone IDs, list mission rewards without a commendation price). Removed
the page, its sidebar entry, its /api/maintenance/* routes, the
`maintenance` permission and the two database calls only it used
(GetAllPetNames, FixPropertyCloneIds). The scheduled tasks (lift expired
bans, fill in pet owners, approve known pet names) and property model
import/removal stay.
Check: the Admin sidebar group has no Maintenance link; /maintenance is
a 404; the Tasks page still lists "Approve known pet names" and "Fill in
pet owners"; property import still works; the Permissions page no
longer lists "Data maintenance".
