v0.7.1

Added

• Dashboard: a Message Analytics section — a period selector (24h / 7d / 30d) with messages-over-time, messages-by-type, and top-chats charts, sourced from the existing statistics endpoints. The charting bundle is code-split so it loads only with the Dashboard, not on the login screen.
• Infrastructure: an Engine Configuration tile to pick and configure the active WhatsApp engine (whatsapp-web.js / Baileys), mirroring the Database tile. Selecting an engine persists the choice and applies on restart.

Changed

• Dashboard: the Messages Today card is now populated from real data, and the previously-empty API Calls card is replaced with a Total Messages metric. The sidebar version is now read live from the backend, so a stale-built bundle no longer shows the wrong version.
• Plugins: the WhatsApp engine adapters are no longer listed as plugin cards — they are configured under Infrastructure → Engine. The Plugins page is now extensions-only.
• Plugins config dialog: the Configuration/Sessions and install tabs use a cleaner segmented control; the modal caps its height and scrolls its body with a pinned header and footer (Save is always reachable) and is wider for config-heavy plugins.
• ⚠️ Deployment: the bundled docker-compose files no longer pin ENGINE_TYPE, so the active engine can be chosen from Infrastructure → Engine (persisted to data/.env.generated). A real container/host ENGINE_TYPE env still takes precedence; leave it unset to let the dashboard control the engine.
• Docker Compose: the production data-path settings (SESSION_DATA_PATH, STORAGE_LOCAL_PATH, PLUGINS_DIR) and the dev-compose environment are now overridable via ${VAR:-default} without editing the compose files. (#450, #451 — thanks @MS-Jahan)

Fixed

• Chats: voice notes and videos now play — the Content-Security-Policy was missing a media-src for data: URIs, so the browser blocked inline audio/video.
• Chats: stickers, images, videos and documents loaded from history now render instead of collapsing to an empty timestamp-only bubble (history is fetched with its media payload).
• Chats: on small screens the conversation back-button icon is now visible (inherited button padding had squeezed it to zero width).
• Plugins config dialog: radio buttons on the Sessions tab no longer stretch to full width and strand their labels.
• Infrastructure: the engine status and the engine config form now reflect the real saved headless / session-path / browser-argument values instead of always showing defaults.
• Docker (production builds): the builder stage now forces devDependencies (npm ci --include=dev) so nest build and the dashboard build no longer fail with nest: not found when a PaaS (e.g. Coolify) leaks NODE_ENV=production into the image build. (#449 — thanks @MS-Jahan)
