Add daily beta build publish script

  Builds multi-arch Docker image from the current APP_VERSION in config.py
  and pushes to GHCR + Docker Hub, overwriting the same beta tag. Creates
  or updates a GitHub prerelease with changelog notes. Users re-pull the
  tag or use Watchtower to get daily updates. Supports --parallel,
  --ghcr-only, --dockerhub-only, and --skip-release flags. Documents
  daily beta builds in README and DOCKERHUB.md.

CHANGELOG.md

@@ -12,7 +12,7 @@ All notable changes to Bambuddy will be documented in this file.
 - **SpoolBuddy AMS Page: External Slots & Slot Configuration** — The SpoolBuddy AMS page (`/spoolbuddy/ams`) now displays external spool slots (single nozzle: "Ext", dual nozzle: "Ext-L"/"Ext-R") and AMS-HT units in a compact horizontal row below the regular AMS grid, fitting within the 1024×600 kiosk display without scrolling. Clicking any AMS, AMS-HT, or external slot opens the `ConfigureAmsSlotModal` to configure filament type and color — the same modal used on the main Printers page. Dual-nozzle printers show L/R nozzle badges on each AMS unit. Temperature and humidity are displayed with threshold-colored SVG icons (green/gold/red) matching the Bambu Lab style on the main printer cards, using the configured AMS humidity and temperature thresholds from settings.
 - **SpoolBuddy Dashboard Redesign** — Redesigned the SpoolBuddy dashboard with a two-column layout: left column shows device connection status (scale and NFC with state-colored icons — green when device is online, gray when offline) and a compact printers list with live status indicators; right column shows the current spool card. Cards use a dashed border style for a cleaner look. The large weight display card was removed in favor of the inline scale reading in the device card.
 - **SpoolBuddy Kiosk Auth Bypass via API Key** — When Bambuddy auth is enabled, the SpoolBuddy kiosk (Chromium on RPi) was redirected to the login page because the `ProtectedRoute` requires a user object from `GET /auth/me`, which only accepted JWT tokens. The `/auth/me` endpoint now also accepts API keys (via `Authorization: Bearer bb_xxx` or `X-API-Key` header) and returns a synthetic admin user with all permissions. The frontend's `AuthContext` reads an optional `?token=` URL parameter on first load, stores it in localStorage, and strips it from the URL to prevent leakage via browser history or referrer. The install script now includes the API key in the kiosk URL (`/spoolbuddy?token=${API_KEY}`), so the device authenticates automatically on boot without manual login.
-- **Daily Beta Builds** — Added a release script (`docker-publish-daily-beta.sh`) that automates the full beta release workflow: version bump, changelog date update, git tag, multi-arch Docker build+push to both GHCR and Docker Hub, and GitHub prerelease creation with changelog notes. Beta images use version tags (e.g., `0.2.2b2`) and are never tagged as `latest`. Users can opt in to beta update notifications via Settings → Updates → "Include beta versions".
+- **Daily Beta Builds** — Added a release script (`docker-publish-daily-beta.sh`) that reads the current `APP_VERSION` from config, builds a multi-arch Docker image, pushes to both GHCR and Docker Hub, and creates/updates a GitHub prerelease with changelog notes. Daily builds overwrite the same beta version tag (e.g., `0.2.2b1`) — users pull the latest by re-pulling the tag or using Watchtower. Beta images are never tagged as `latest`.
 
 ### Fixed
 - **Printer Card Loses Info When Print Is Paused** ([#562](https://github.com/maziggy/bambuddy/issues/562)) — When a print was paused (via G-code pause command or user action), the printer card showed the print as finished — the progress bar, print name, ETA, layer count, and cover image all disappeared, replaced by the idle "Ready to Print" placeholder. The display conditions only checked for `state === 'RUNNING'` but not `'PAUSE'`, even though other parts of the same page (Skip Objects button, Stop/Resume controls) already handled both states correctly. Now shows print progress info for both `RUNNING` and `PAUSE` states, and the status label correctly reads "Paused" instead of the hardcoded "Printing" fallback.
