Language comes from the gnexus-auth account profile by default; Settings
now hosts a per-service override that survives logouts and profile-webhook
syncs (users table keeps profile JSON verbatim, override in a separate
column that the upsert never touches). Open mode stores the choice in
localStorage.

- backend: users table (zero-migration, IF NOT EXISTS), app/locales.py
  (normalize_locale/effective_locale), users upsert on session create and
  user.updated webhook, GET /me returns locale + locale_effective,
  new PATCH /api/v1/me (cookie-session only; 'auto'/'""' clears override)
- frontend: hand-rolled i18n mirror of gnexus-creds (locale ref, t() with
  Slavic plurals, EN fallback), full dictionaries (~130 strings), <html
  lang> + <title> tracked via watch; SettingsPage with language picker
  (Auto/en/uk/ru); ServerCard/ServerPage/StoragePage status triple and
  table columns unified into reactive computed t() lookups; fmtAgo/
  fmtUptime localized; nav/login/shell translated; default html lang en

Backend: shares + share_samples tables, background probe loop
(os.statvfs every GHARD_SHARE_INTERVAL, 7-day retention, ok=0 when
the mount is unreachable), CRUD + samples API, instant first sample
on create/update, shares in MCP panel_overview.

Frontend: /storage page — share cards with status badge/progress/
used-free-total, 24h fill chart, add/delete via modal + confirm.
ChartLine shows a visible point while there are fewer than 3 samples.

README: CIFS/NFS mount + fstab examples, GHARD_SHARE_INTERVAL row.
