feat: Add TanStack table for pipeline executions with debug modal

- Create ExecutionsView component with TanStack Table
- Add status filter buttons with count badges
- Add action buttons: Analytics, Metrics, Debug
- Add debug modal with AI copy-paste button for failed executions
- Generate detailed debug report with stage metrics and error context
- Update executions page to use new component

+- This is a ReviewIQ pipeline execution
+- Pipeline stages: normalize → classify → route → aggregate
+- The classify stage uses OpenAI/Anthropic for URT classification
+- Common failure points: API rate limits, database connection, invalid input data
+
+### Suggested Investigation
+1. Check if error is related to LLM API (rate limiting, auth, timeout)
+2. Check database connectivity issues
+3. Review input data validity
+4. Check stage metrics for which stage failed and why
