feat(agentic): add real-time dashboard with Livewire components (#96)
Add a live agent activity dashboard to the Core App Laravel frontend.
Provides real-time visibility into agent fleet status, job queue,
activity feed, metrics, and human-in-the-loop actions — replacing
SSH + tail -f as the operator interface.
Dashboard panels:
- Agent Fleet: grid of agent cards with heartbeat, status, model info
- Job Queue: filterable table with cancel/retry actions
- Live Activity Feed: real-time stream with agent/type filters
- Metrics: stat cards, budget gauge, cost breakdown, throughput chart
- Human Actions: inline question answering, review gate approval
Tech: Laravel Blade + Livewire 4 + Tailwind CSS + Alpine.js + ApexCharts
