[ASTERIXDB-3593][UI]: Support multi-statement responses in dashboard

- user model changes: no
- storage format changes: no
- interface changes: no

details:
- The response shape follows the request's content, so the dashboard
  has to read both: flat for one real statement, statements[] for
  more. The new shared/utils/response.utils.ts reads a flat response
  as its own single statement, and every consumer goes through it.
- Single-statement responses are byte-identical, so every request the
  dashboard issues on its own keeps taking the flat path unchanged.
- One result view: the first statement that returned rows, falling
  back to the first carrying plans. Metrics are aggregated with
  elapsedTime as the max, since it is measured from request start,
  and the rest summed; durations are parsed unit-aware and formatted
  the way Duration.formatNanos does.
- A statement failing partway through a batch returns HTTP 200, so
  its errors are lifted out of statements[] to the error path.
