improvement(processing): replace as any casts with proper types in logging

- logger.ts: cast JSONB cost column to `WorkflowExecutionLog['cost']` instead
  of `any` in both `completeWorkflowExecution` and `getWorkflowExecution`
- logger.ts: replace `(orgUsageBefore as any)?.toString?.()` with `String()`
  since COALESCE guarantees a non-null SQL aggregate value
- logging-session.ts: cast JSONB cost to `AccumulatedCost` (the local
  interface) instead of `any` in `loadExistingCost`
