shankar0123 b8fac59200 chore(fmt): gofmt cleanup on files touched by audit-2026-05-11 fix bundle
Whitespace alignment drift surfaced by gofmt -l after merging 7 fix branches.
Pure formatting, no semantic change. Pre-existing master drift in
internal/auth/oidc/{domain/types.go, integration_keycloak_rotate_test.go,
test_discovery.go} left untouched — that's separate tech debt.

// ProtocolEndpointPrefixes lists the URL path prefixes that authenticate
// via the protocol itself rather than via certctl's Bearer / cookie
// stack. Bundle 1 Phase 3 uses this allowlist as the explicit "do NOT
// wrap with RequirePermission" set: the RBAC middleware applies only to
// admin handlers replacing legacy IsAdmin checks plus any new
// permission-gated routes; the endpoints below keep their existing
// protocol-level auth.
//
// Adding a new protocol endpoint that doesn't take a Bearer token MUST
// also add the prefix here and a parallel test in Phase 12 asserting
// the route is unwrapped.
//
// Per the Phase 3 audit:
//
// ACME server : /acme/profile/<id>/* + /acme/* (JWS-signed, RFC 8555).
// SCEP server : /scep (challenge password +
// signed CSR, RFC 8894).
// EST server : /.well-known/est/* (mTLS client cert,
// RFC 7030).
// OCSP responder : /.well-known/pki/ocsp (RFC 6960, public).
// CRL distrib. : /.well-known/pki/crl/* (RFC 5280, public).
//
// Plus the existing public-route bypass list at internal/api/router
// (router.go:69-72): /health, /ready, /api/v1/auth/info. Those bypass
// EVERY middleware stack, not just RBAC, so they're not in this
// allowlist; they're handled in router.go directly.
// Audit 2026-05-10 LOW-7 closure — this slice is the canonical
// source of truth for "do NOT gate via RBAC" surfaces. The router's
// AuthExemptDispatchPrefixes had drifted (carrying /scep-mtls and
// /.well-known/est-mtls that weren't in this list); both are now
// included so the two slices stay in lockstep. A CI guard
// (scripts/ci-guards/protocol-endpoint-prefix-sync.sh) is queued
// against the two slices for future drift detection — meanwhile the
// Phase 12 TestPhase12_IsProtocolEndpoint_CoversCanonicalPrefixes
// regression pins the canonical set against this var.
