refactor(admin): split consent-management, control-library, incidents, training pages

Agent-completed splits committed after agents hit rate limits before
committing their work. All 4 pages now under 500 LOC:

- consent-management: 1303 -> 193 LOC (+ 7 _components, _hooks, _data, _types)
- control-library: 1210 -> 298 LOC (+ _components, _types)
- incidents: 1150 -> 373 LOC (+ _components)
- training: 1127 -> 366 LOC (+ _components)

Verification: next build clean (142 pages generated).
