v0.4.0

• Pages no longer flash "No vehicles found", empty charts, or other empty
  states while loading. Panels show placeholders at their final size, values
  render in your units from the start, and switching ranges keeps the previous
  chart until the next one loads.
• Live charging stats appear immediately after a page refresh.
• Redesigned sign-in and onboarding screens, including a six-digit
  verification code input that accepts paste and one-time-code autofill and
  submits automatically.
• Stronger app password requirements: new passwords need at least 12
  characters and can't be common passwords, the app name, or patterns like
  1234, with a live strength meter. Existing passwords keep working.
• Settings → About shows the running version and build commit.
• Updated all dependencies to their latest versions, with no known
  vulnerabilities.
• Faster multi-platform Docker builds.

Upgrading

Back up Postgres before updating, preserve your existing APP_SECRET and
database volume, then run docker compose pull && docker compose up -d.

Docker image tags have changed. latest now means the newest stable release
and is the default in docker-compose.yml; pin a line with 0.4 or an exact
release with 0.4.0. Builds of every main commit are now published as edge
instead of latest.

If you set APP_PASSWORD and the app has no password yet, it must meet the new
password requirements or the server will refuse to start. It's ignored once a
password exists.
