feat(sekoia): Sekoia XDR + SEKOIA Intelligence Center integrations

Sekoia XDR (siem): alert ingestion (list_alerts) with an exhaustive OCSF mapper
and a bundled 'Sekoia XDR Alert' default type, plus 20 commands across alerts
(list/get/search, status workflow, comments), event search jobs (create/status/
results + one-shot search_events), cases, asset management, users, kill chains
and a generic authenticated HTTP passthrough. Bearer-token auth, EU host default.

SEKOIA Intelligence Center (enrichment): observable/indicator/indicator-context
CTI queries plus ip/url/domain/file/email reputation lookups (STIX type resolved
automatically). No fetch.
