The database_usage task (hourly) measures on the background connection,
checks the free space on the database's disk (database_disk_path, else the
SQLite file or a local MySQL data directory) and alerts once when it drops
under database_disk_warn_percent. Log pruning keeps database_usage_days.
GET /api/database/usage?range=day|week|month. The settings are on the
Settings page.
