UI/UX lucene search form tweaks

[hextraza]

• Hidden/unhidden columns reset on filtration
• Rename "Filter" to "Search"
• Add a filter state button for searchString=all
• Loading circle during queries
• None values in filter form can lead to odd behavior
• Going from "in-set" to another operator doesn't immediately reset the select box
• ExternalVariantWidget Dialog needs margin/better styling
• is empty/is not empty should not allow for an entered value
• Make forward/backward consistently rerender the table
• CADD_PH treated as string
• For the start/end/position columns, add a JEXK format string to format with commas. Ensure the grid adds a valueFormatter or some similar hook to use this. Ensure the result sorts correctly (i.e. sorts on the raw value, not formatted string). There is a stub here:

  DiscvrLabKeyModules/jbrowse/src/client/JBrowse/utils.ts

  Line 476 in 1e39c92

  // TODO: can we pass the JEXL format string here? How does this impact filter/sorting?

• Make header tooltip text 8px->18px
• variableSamples value is truncated when filter is applied on Filter form (not on the filter status button)
• Create a function for "serializeLocationToLuceneQuery", which takes the location (contig/start/end) and write that into a string that we could append to the URL. Then use this in the URL generated by the Variant Table button for "change to free-text search"

This is not strictly lucene, but if we're going to keep the original table widget, we should fix the styling on value:

Example test URL: http://localhost:8080/labkey/home/jbrowse-variantTable.view?session=mgap&trackId=mgap_hg38&location=1:1..430419

More on that styling. In the screenshot below, if I disable the marginDense margin-top:8px directive, it fixes the misalignment. Unsure if this is actually the best place to edit, but maybe this gives a clue what to update:

This styling issue is fixed
