feat(databases): backup import — upload .tar.gz as a restore point

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.

 ## 9b. Phase I — Companion surfaces
 
-- [ ] **Phone app** — read-heavy mobile client over the existing API
-  (PAT auth already works). Scope v1: project/service list, status,
-  deploy trigger + log tail, restart/stop, notifications push via
-  existing notification rows (APNs/FCM relay optional, self-hosted
-  webhook → ntfy/Gotify as zero-infra alternative). React Native or
-  native-lean PWA; the API surface is already agent-shaped so the app
-  is a thin client. Design: dark UI, deploy status as first-class view.
+- [ ] **Phone app** — fully-featured companion, not a read-only viewer.
+  The target: a user on the go can see a problem, understand it, and
+  fix it without a laptop. PAT + profile auth (multi-instance like the
+  CLI).
+  - **Dashboard** — project/service status at a glance, deploy
+    activity, node health, resource usage (cpu/mem from existing
+    metrics endpoints).
+  - **Operate** — deploy, redeploy, restart/stop/start, rollback to a
+    prior deployment, cancel a running deploy, scale replicas.
+  - **Observe** — live log tail (SSE), deployment step logs, backup
+    status, cron execution history.
+  - **Fix** — env var edit + apply-redeploy, domain add/remove,
+    maintenance-mode toggle, database backup/restore trigger.
+  - **Notifications** — push via existing notification rows; zero-infra
+    path = self-hosted ntfy/Gotify relay (no Firebase dependency),
+    FCM/APNs optional.
+  - **Stack** — React Native (Expo) thin client over the agent-shaped
+    API; dark UI mirroring the web design system; deploy status as the
+    first-class view. Ships with `app/` workspace in this repo.
 - [ ] **Status/offline resilience** — app + CLI degrade gracefully when
   the instance is unreachable (cached last-known state, clear banner).

+        application/gzip body) to create a new restore point. The archive
+        lands in the backup volume and, when a backup target is assigned,
+        is also shipped offsite. Managed databases only; 2 GiB ceiling.

 - **External databases**: `POST /databases/register-external` (probes first; `{name,type,host,port,database,username,password,ssl}`), `POST /databases/test-connection` (ad-hoc probe → `{ok,latency_ms,error}`), `POST /databases/{id}/test-connection` (re-probe with stored credentials). Rows carry `provider:"external"` + `external{host,port,database,username,has_password,ssl}`; passwords encrypted at rest, never returned. Lifecycle actions and backups reject external rows — no container exists.
 - **Public DB port**: managed databases bind `127.0.0.1` by default; `public_port:true` on create or `PUT /databases/{id} {public_port}` binds `0.0.0.0`. Toggling recreates the container — the data volume persists.
 - **Backup targets**: S3-compatible destinations (`/backup-targets` CRUD + `POST /backup-targets/{id}/test`). Endpoints/buckets are probed before storing; keys encrypted at rest (`has_credentials` only). Assign via `PUT /databases/{id} {backup_target_id}` — empty string clears; external databases reject assignment. Managed backups stay local; a copy ships to `[prefix/]databases/<db-id>/<archive>` and rows expose `remote:true`. Restore prefers the local archive and falls back to the remote object. Deleting a target is refused (409) while databases reference it.
+- **Backup import**: `POST /databases/{id}/backups/import` — upload a `.tar.gz` (multipart `file` or raw `application/gzip` body, ≤2 GiB) to create a restore point; also ships offsite when a target is assigned. CLI: `databases import-backup <id> <file|->`.
 - **Identifiers**: all ids are UUIDs. Tokens: `cnp_` user PATs, `cagt_` agent onboarding tokens.
