feat(V2.2): bulk revocation — filter-based fleet-wide certificate revocation

Add POST /api/v1/certificates/bulk-revoke with filter criteria (profile_id,
owner_id, agent_id, issuer_id, team_id, certificate_ids), partial-failure
tolerance, and audit trail. Includes MCP tool, CLI command (certs bulk-revoke),
server-side bulk modal in GUI replacing client-side sequential loop, OpenAPI
spec, compliance mapping updates, and 21 new tests (12 service, 7 handler,
1 CLI, 1 frontend).
