feat: trace data indicators, inline tap config, and detail tab gating

Trace data visibility:
- ProcessorNode now includes hasTraceData flag computed from captured
  body/headers during tree conversion
- ConfigBadge shows teal for tracing configured, green when data captured
- Search results show green footprints icon for exchanges with trace data
- New has_trace_data column on executions table (V11 migration with backfill)
- OpenSearch documents and ExecutionSummary include the flag

Inline tap configuration:
- Extracted reusable TapConfigModal component from RouteDetail
- Diagram context menu opens tap modal inline instead of navigating away
- Toggle-trace action works immediately with toast feedback
- Modal closes only on ESC, Cancel, Save, or Delete (not backdrop click)

Detail panel tab gating:
- Headers, Input, Output tabs disabled when no data is available
- Works at both exchange and processor level
- Falls back to Info tab when active tab becomes empty
