Add a SigNoz connector so its organization members can be pulled into
access-review campaign snapshots. SigNoz authenticates with a
SIGNOZ-API-KEY admin service-account key and a customer-supplied base
URL (a SigNoz Cloud region/tenant host or a self-hosted instance).
The driver lists users via GET /api/v1/user, which returns the role
(ADMIN/EDITOR/VIEWER) inline so admin detection works in a single call,
and maps the SigNoz user status (active / pending_invite / deleted) to
the account active flag. The name resolver reads the organization
display name from GET /api/v2/orgs/me to title the access source.
Wire the provider through the coredata enum and settings, the
connector-provider registry (driver and name-resolver factories), the
console API-key input schema and validation, the access-review source
label, and the SigNoz brand logo.
