feat: add 5 new vendor modules and fix dialyzer issues

Vendor modules added:
- Aviat (WTM microwave radios)
- Aruba (wireless controllers and APs)
- CiscoWLC (Cisco wireless LAN controllers)
- Teltonika (RUTOS LTE routers)
- Sub10 (mmWave backhaul radios)

Dialyzer fixes:
- Fix unknown type Devices.t/0 in alert.ex and device.ex
- Fix unmatched_return warnings across multiple files
- Add :exq to PLT for Exq function detection
- Remove dead code in base.ex, dynamic.ex, vendor.ex
- Fix Device.t() type spec to allow nil name field

Tests: 1437 tests, 0 failures
Dialyzer: 0 errors
Credo: no issues
