Make nmon easier to install and run without editing YAML by hand: - Settings: point-and-click forms over config.yaml (GET/PUT /api/v1/settings/form); the YAML editor moves to /settings/yaml. - First install: with no sign-in configured nmon starts in install mode, serves only the setup wizard (sign-in, basics, devices, alerting) and closes it for good once sign-in is saved. A self-signed certificate is generated when no TLS source is given. poller.interval becomes a config setting. - Reverse proxies: opt-in --http-listen plain-HTTP listener beside HTTPS; sign-in stays required. - Webhooks: Generic, Teams Adaptive Card, Slack and Discord presets, template preview and test send. - Help: the operations, coverage and profile docs served at /help. - Polling: per-device "Poll now", a dry-run test poll returning an SNMP trace, and time-limited in-memory SNMP debug recording, in the UI and as `nmon device poll`. - Ansible: deploys into install mode when no sign-in is set, and no longer overwrites the config.yaml the wizard wrote.
