[9.x] Fix date filter between operator not working in runway listing

[albinameti00]

Problem

When filtering a Runway resource listing by a date field using the between operator,
the filter is silently ignored and all results are returned unfiltered.

This is because isComplete() only checks for the value key, but the between
operator sends range_value instead:

• after / before → { "operator": ">", "value": "..." }
• between → { "operator": "between", "range_value": { "start": "...", "end": "..." } }

So isComplete() always returns false for between, preventing the filter from ever being applied.

Fix

Add a between case to isComplete() that checks for range_value.start and range_value.end.
