Closes #2112 /claim #2112 Summary Adds an snmp provider that ingests forwarded SNMP trap data as JSON through Keep’s existing webhook event endpoint.

This implementation is intentionally scoped to forwarded JSON trap ingestion only. It does not add a native UDP listener or a Keep-side SNMP runtime dependency.

What changed Added snmp webhook provider, trap OID to alert name/severity mapping, stable fingerprint generation using fingerprint or source_address|trap_oid|entity_id, batch JSON payload support, provider docs and generated snippet and unit tests for parsing, mapping, and fingerprint behavior.
