D5. POST /databases/:id/backups/import accepts a gzipped tar archive
(multipart `file` field or raw application/gzip body, 2 GiB ceiling),
stages it to a temp file, streams it into the backup volume via the
started holder container, and registers a completed backup row — a
first-class restore point that also ships offsite when a target is
assigned. External databases rejected.
Also fixes `containr databases restore` — it never sent database_id,
which the API requires, so every CLI restore failed validation.
CLI: databases import-backup <id> <file|-> (stdin support via new
client.DoRaw). UI: Import button in the backups row. OpenAPI + docs.

Deep analysis of dflow (~43 queue processors, ~30 collections, ~180
server actions) mapped against Containr, sectioned into phases A–G.
Phase A (agent spine) is in progress — this commit adds PATs.
