feat: M13 — GUI operations (bulk ops, deployment timeline, policy editor, target wizard, audit export, short-lived creds)

Bulk certificate operations: multi-select checkboxes on certificates list with
bulk action bar for triggering renewal, revocation (with RFC 5280 reason modal
and progress bar), and owner reassignment across selected certificates.

Deployment status timeline: visual 4-step lifecycle pipeline (Requested → Issued
→ Deploying → Active) on certificate detail page, powered by per-cert job queries
with animated status indicators for active steps and failure states.

Inline policy editor: edit/save/cancel interface on certificate detail page for
changing renewal policy and certificate profile assignments via dropdown selectors
with lazy-loaded policy and profile lists.

Target connector configuration wizard: 3-step modal (Select Type → Configure →
Review) with type-specific configuration fields for NGINX, Apache, HAProxy, F5
BIG-IP, and IIS targets including required field validation.

Audit trail export: CSV and JSON download buttons on audit page with applied
filters preserved in export. Added action filter input for narrower searches.

Short-lived credentials dashboard: new page at /short-lived showing ephemeral
certificates (profile TTL < 1 hour) with live TTL countdown, auto-refresh every
10 seconds, profile lookup, and stats bar (active/expired/profiles).

DataTable enhanced with optional selectable/selectedKeys/onSelectionChange props
for checkbox multi-select with select-all toggle and row highlighting.

Frontend tests expanded from 53 to 79: full API client endpoint coverage for
profiles, owners, teams, agent groups, revocation, approval/rejection, policy
violations, and issuer creation.
