Adds a vendor-agnostic radio-state extractor that lets the frequency-
aware rules actually fire on production data without per-vendor
plumbing for each profile.
- Towerops.Snmp.RadioState — pure module that maps a frequency in MHz
to the corresponding 802.11 channel across 2.4 GHz, 5 GHz, and 6 GHz
bands; reads the freshest "frequency" sensor (already emitted by
Cambium/MikroTik/AirOS/Mimosa/Exalt/etc. profiles) and persists the
AP-level current_frequency_mhz, current_channel, last_radio_seen_at
fields onto snmp_devices.
- DevicePollerWorker now calls RadioState.update_from_sensors/1 after
each sensor poll so frequency-aware rules read a single canonical
source instead of joining sensors at query time.
- Towerops.Recommendations.Rules.OwnFleetChannelConflict — new rule
that needs no neighbor-scan collection: detects when 2+ of our own
APs at the same site share a channel (self-interference). One
insight per (site, channel) with a clickable list of conflicting
APs and their channel widths. Critical when 3+ APs share a channel.
- Insight.@valid_types extended with own_fleet_channel_conflict.
- UI: amber card showing channel, frequency, AP count, and the linked
list of conflicting devices.
