refactor(admin): split dsr/new, compliance-hub, iace/monitoring, cookie-banner pages

Extract components and hooks from 4 oversized pages (518–508 LOC each) to bring
each page.tsx under 300 LOC (hard cap 500). Zero behavior changes.

- dsr/new: TypeSelector, SourceSelector → _components/; useNewDSRForm → _hooks/
- compliance-hub: QuickActions, StatsRow, DomainChart, MappingsAndFindings,
  RegulationsTable → _components/; useComplianceHub → _hooks/
- iace/[projectId]/monitoring: Badges, EventForm, ResolveModal, TimelineEvent →
  _components/; useMonitoring → _hooks/
- cookie-banner: BannerPreview, CategoryCard → _components/; useCookieBanner → _hooks/

Result: page.tsx LOC: dsr/new=259, compliance-hub=95, monitoring=157, cookie-banner=212
