fix: correct airfiber SNMP OIDs to match MIB table definitions

Browse source 
All 7 OIDs were reading from wrong SNMP table/columns. Frequency and
power config values pointed at the status table instead of the config
table, and capacity/signal columns pointed at unrelated fields like
radio temperature and boolean flags.

Corrected OIDs to match UBNT-AirFIBER-MIB structure:
- Frequency/power: config table (.3.1) entries 5, 6, 9
- Signal: status table (.3.2) entries 11, 14
- Capacity: status table (.3.2) entries 5, 6 with 1M divisor
