applyMissingMigrations ran the entire migration SQL as one transaction,
which rolled back all changes when any statement failed (e.g. adding a
NOT NULL column to a non-empty table). Replaced with prisma db push
which compares the schema and applies only what's needed. Also added
support for importing .sql files (not just .zip) in auto-import.

Adds autoImportEnabled/autoImportHour to rclone config. A separate
hourly cron finds the latest .zip in backups/ and restores it to the
database (drop schema, psql restore, apply migrations). Frontend shows
toggle + time picker + Import Now button in the Receiver PC section.
