SNMP devices added without a profile (e.g., via simplified add flow)
were failing with "no SNMP profile assigned". Now falls back to the
generic-snmp profile which collects standard MIB-II metrics.

- SNMPCollector implements poller.Collector interface
- Profile-driven OID collection: scalars via Get, tables via Walk/BulkWalk
- BulkWalk wrapped in withTimeout to prevent indefinite hangs
- SNMPv1 uses Walk, v2c/v3 uses BulkWalk (MaxRepetitions=10)
- Safety valve: walkTable aborts at 10,000 PDUs per walk
- Counter delta computation via CounterCache for rate metrics
- Standard metrics routed to DeviceMetricsEvent (interfaces, health)
- Custom metrics routed to SNMPMetricsEvent (snmp_custom)
- DeviceStatusEvent published with online/offline status
- Each poll group collects independently (partial failure tolerant)
- Credential resolution via GetRawCredentials + ParseSNMPCredentials
- ifXTable Counter64 data supersedes ifTable Counter32 via PreferOver
- ssCpuIdle invert_percent transform for CPU load fallback
