Jon Chery 5232fcb808 fix(P04): wire ACL enforcement + WebAuthn reg auth + audit actor (REQ-153)
R-023: Zero-trust enforcement operationally wired.

ACL enforcement (C-45 staged rollout):
- acl.Check wired into all 5 daemon handlers (dispatch/jobs/nodes/tasks)
- health endpoints exempt (liveness probes not gated)
- ACL log-only mode default (config acl.enforce=false); enforce after
  bootstrap ACL verified
- sshpush auth: ORCA_OIDC_TOKEN validated against JWKS before apply
- txn apply: Authorize hook validates OIDC token before running pull
- acl.json mode 0600 (was 0644)
- flock on acl.json for concurrent grant/revoke
- bootstrap ACL: init grants cluster-admin to orca-admins group + SVID

Audit actor identity:
- currentActor reads OIDC sub from credentials.json (was hardcoded "cli")
- threaded through all audit.Record calls via context

WebAuthn registration auth:
- BeginRegistration/FinishRegistration require authenticated session
- fail-closed 401 when no authFunc configured

// Package sshpush — auth.go provides the operator OIDC token
// validation hook used by SSH-push apply paths (P04, v0.13; C-44).
//
// The SSH-push transport moves state to peers (systemd units, nft
// rules, drain commands, txn bundles). Any state-changing apply
// MUST validate $ORCA_OIDC_TOKEN against the issuer's JWKS before
// touching a peer. This file exposes AuthorizeApply, a helper the
// CLI calls before fan-out; the actual JWKS verification is in
// internal/identity.VerifyOperatorToken (kept there to centralize
// the OIDC client logic).

// JWKS and returns the verified operator actor string ("oidc:<sub>")
// for audit logging. Returns an error if the token is missing or
// invalid; the caller MUST refuse the apply in that case.
//
// When issuer is empty, the function returns an error — apply paths
// require an OIDC issuer to be configured. The clientID defaults to
// "orca-cli" when empty.
