app/vmui/logs: fix missing field values in auto-complete

[arturminchukov]

Describe Your Changes

Related issue: #8749 Added query to requests /field_names and /field_values to get more precision results:

• If filterName is _msg or _stream_id, the query cannot be generated specifically, so a wildcard query ("*") is returned.

• If filterName is _stream, the query is generated using regexp ({type=~"value.*"}).

• If filterName is _time, a simplified query is created by trimming the value up to the first occurrence of a delimiter such as - or :.

• For all other values of filterName, a prefix query is returned using the query value with a * appended (e.g., "value*").

Related issue: #8806 Enhanced autocomplete with parsed field suggestions from unpack pipe.

It would be nice if you could include other logical operators like :-, :!, :=. For example, you could write field:- "e", field:=word, or field:!info. Currently, the autocomplete trigger only activates with field:, so when you need to exclude something, you have to move the cursor again to add these operators.

Thanks for comment! Added it now.
