feat(gui): add create modals for issuers, policies, profiles, owners, teams, agent groups

Six pages were read-only viewers despite the API client having all
create functions wired up. Users deploying certctl had no way to create
CAs or other objects from the GUI — reported in GitHub issue.

- IssuersPage: 2-step create modal (type selection → config) for
  Local CA, ACME, step-ca, OpenSSL/Custom issuer types
- PoliciesPage: create modal with type, severity, JSON config, enabled
- ProfilesPage: create modal with name, description, max TTL, short-lived
- OwnersPage: create modal with name, email, team dropdown
- TeamsPage: create modal with name, description
- AgentGroupsPage: create modal with match criteria fields
- Layout.tsx: version v2.0.5 → v2.0.7
- cmd/server/main.go: version 0.1.0 → 2.0.7
