Makes live monitoring (and therefore alerting) genuinely 24/7 and
restart-surviving, instead of runtime-only keepalive.
- NL43Config.monitor_enabled (default True) + migrate_add_monitor_enabled.py.
- On startup, auto-start keepalive monitors for every monitor_enabled +
tcp_enabled unit — so feeds/alerts resume after a restart with no manual step.
- /monitor/start and /monitor/stop now PERSIST monitor_enabled (start=True,
stop=False) in addition to applying keepalive at runtime, so the toggle
sticks. Roster output includes monitor_enabled for the admin UI to read.
On by default: configure a unit -> it's monitored 24/7 unless toggled off.
