v0.17.0

Added

• Remove an agent from the UI. Deleting the monitor of a machine whose agent is
  online and accepts commands offers to remove the agent automatically: it stops
  and removes its service, binary and configuration (as --uninstall does), then
  the monitor is deleted. Administrator session only, recorded in the audit log
  (POST /api/targets/{id}/agent/uninstall). An agent in a container, or not
  installed by the install scripts, refuses; the manual commands stay available.
• Synology package, deeper. The DSM 7 package is attached to every release
  (x86_64 and aarch64) and the agent reads RAID and volume health, disks (model,
  temperature, wear, unreadable sectors), installed packages, SMB/NFS/SSH and the
  UPS, with alert rules for a degraded array, a read-only volume, a hot disk, growing
  bad sectors, SSD wear and a stopped package. The add-monitor page offers the package
  or the credentials, with the pin ready to copy.
• Pre-releases from dev. A tag vX.Y.Z on a commit that is not on main publishes
  a pre-release (images, agent binaries, .spk), never latest.
• Deeper integrations and more alert rules for Proxmox VE, Proxmox Backup Server,
  TrueNAS, UniFi, OPNsense, Tailscale, Pi-hole, AdGuard Home, Home Assistant, Jellyfin,
  Plex, Immich, Nextcloud, PostgreSQL and Synology (API): about 100 new default rules
  and many new metrics (certificates, backups, replication, DHCP, quotas, jobs, safety
  sensors, tasks and more). Field names come from the vendors' public APIs.
• Motion and feedback. Shared motion tokens, softer menus, toasts and panels, and a
  green confirmation on the action buttons when the action succeeded.

Changed

• Cleaner monitor pages. Icon-only header actions with a gear for the settings, a
  lighter title line, and the agent settings (relay, logs, sentinel, services to watch,
  re-enrolment) moved to the monitor's settings. The "Allow re-enrolment" button acts
  in one click.
• Simpler settings. Six tabs (the former General tab is now in System), a password
  form behind a button, empty blocks collapsed, and no on-call contacts or hours in My
  account.
• No default site. A device without a site stays "No site"; only devices with a site
  appear on the map, and there is no map until a site exists. The NAS fleet view is
  gone: filter the monitors list instead.
• The documentation lives on the website. The app no longer carries help texts: each
  screen has a link to its page on dumbmonit.app/docs, rewritten step by step.
• Home banner. The pigeon is the one of the logo, sitting in the sky.

Fixed

• The agent troubleshooting commands, the Docker Compose block and a one-click
  re-enrolment on the agent install page.
• The Synology installer's fields are readable, and its pin comes from the add-monitor page.
