feat: reorder first/latency in seconds, add effort column

- logs columns are now Key | Account | Model | Effort | Type | Tokens |
  Cost | First | Latency | Tok/s | Time
- First and Latency render in seconds (5.3s) instead of milliseconds
- Effort shows the request reasoning_effort (- when absent) and is
  filterable; the detail line appends it to the model as model (effort)
