fix: prevent double-wrapping of WebPortInspectionError and remove unused extraWebPortCount

- In WebPortInspector, the mapError handler now checks if the error
  is already a WebPortInspectionError (via _tag) and passes it through,
  preserving the original 'HTTP probe timed out' detail instead of
  re-wrapping it with 'Failed to execute HTTP probe request'.

- Remove unused extraWebPortCount field from TerminalRuntimeStatus
  interface and its computation in terminalRuntimeStatus().
