Maintenance log book app — initial scaffold

Multi-department fault log: NewBook-synced room locations + manual
locations with categories, six-state task flow (submitted/in progress/
hold-parts/hold-later/temporary fix/fixed), photos per stage, priorities
with unusable flag and per-task NewBook out-of-order push, costs on
resolve, comment/audit thread, recurring task templates with
note-to-template carryover, asset register, contractor register with
document attachments, staff/contractor allocation, occupancy-aware
summary filter, searchable history with CSV export, email notifications.
