app/vmui: small fixes

Browse source 
* Remove unneeded dependency on `numeral` package
* Properly parse numbers obtained from /api/v1/query_range according to
  https://prometheus.io/docs/prometheus/latest/querying/api/#expression-query-result-formats
* Optimize updating processing the received data from /api/v1/query_range
* Make smoother zoom on `ctrl+scroll`
* Reduce the number of points received from /api/v1/query_range by 2x in order to reduce load on backend
