Motivation
Users need a convenient way to search and filter datasets based on outgassing values after specific time intervals (1h, 10h, 100h, >100h). This PR implements a collapsible accordion interface for these specialized filters to improve data discovery while maintaining a clean UI.

Fixes:
Fixed issue with unit field display based on configuration
Fixed filter display text formatting in collapsed panels
Fixed type error by ensuring unitsEnabled property is properly typed as boolean

Changes:
Added four specialized outgassing filters (1h, 10h, 100h, >100h) using a collapsible accordion interface
Implemented filter forms with operator, value, and unit fields
Added integration with existing scientific condition filter system
Created helper methods for consistent filter formatting and display
Optimized panel layout with stacked title/description for better readability
Consolidated filter processing to work with main Apply button
