feat: ops & UX batch — jobs survive restarts, logs/system in the console, media queue, gallery, chat, exact stream tokens

Fifteen changes aimed at the first day of real use:

- Import and media jobs persist to <data>/jobs-*.json and reload on start
  (running ones settle as errors); the Register button no longer vanishes
  because the gateway restarted.
- Docker ships the cortiq binary (built in the builder stage) — local .cmf
  chat models and image/video generation now work in containers, where
  auto-install never could (no cargo in the runtime image). libvulkan1 added
  for optional GPU offload.
- Open admin console on 0.0.0.0 without a token now warns in the log and
  shows a dismissible banner — the VPS footgun is at least labeled.
- "Restart gateway" button in Settings: stops managed model servers, spawns
  a fresh copy (bind retried while the port frees), Docker relies on the
  container restart policy instead.
- Dashboard "System" panel: CPU sparkline + load, RAM (with the gateway's
  own RSS), free disk at the models dir — sampled by sysinfo every 2 s.
- Featured model cards warn "not enough disk" / "may not fit in RAM" before
  the download, from the same live snapshot.
- Log viewer in the sidebar: a 500-line in-memory ring fed by a second
  ANSI-free tracing layer; filter, level, pause, copy.
- Update check: crates.io polled twice a day, the console shows an
  "update available" notice.
- Media generations queue up (with position shown) instead of being
  rejected; progress gained an honest ETA from measured throughput.
- Generation gallery under the image/video tabs: lazy PPM thumbnails,
  click to reopen with seed/steps, delete.
- Playground chat is a real dialogue now: history is resent, bubbles,
  Clear, Cmd/Ctrl+Enter.
- "Connect your app" snippets (curl / Python / JS) on the keys page, with
  the real key inlined right after creation.
- One-click benchmark on the Models page via `cortiq bench --json`.
- Config export now downloads the actual gateway.toml (comments intact);
  import accepts TOML (validated, hot-reloaded) and the legacy JSON.
- Streaming token counts are exact when the model server provides usage
  (cortiq-server patch, shipped separately); the gateway fallback now
  counts content chunks (1/token on cortiq) instead of chars/4.

Wizard's Finish lands on the Playground. 37 new strings in all 7 languages.
