Logs Explorer: Better performance for loading large volumes of logs, Fixes to Query Builder

Improvements:

• When querying over larger periods of time, if the scan volume exceeded 300GB, the query would time out. It now loads in a couple of seconds.
• Because of which, the smaller queries load even faster now.

Fixes:

• Editing a subsequent value in the chip while searching body would overwrite the first value.
• In some instances, users were unable to remove the body filter.
• At times, all operators would not be visible when clicking on an existing operator in a chip.
• Search dropdown for filters would randomly open.
