chore: regenerate OpenAPI types and remove type assertion hacks

Regenerated schema.d.ts from live backend — now includes slaCompliance
on ExecutionStats/RouteMetrics, filterMatched/duplicateMessage on
ProcessorNode, and all new dashboard endpoints (timeseries/by-app,
timeseries/by-route, punchcard, errors/top, app-settings).

Removed Record<string, unknown> casts that were working around the
stale schema.
