fix: refresh button in sessions hides when we resize the sessions tablele frame to the smallest

[RonenMars]

Description

Fix of: Sessions table filter overflow at minimum width
The bug: When resizing the sessions table to minimum width (15%), changing the filter from "All (0)" to a longer label like "Running (0)" pushed the Refresh button out of view.

Solution:

• Added compact mode that activates when left panel width < 20%
• In compact mode:
  • Filter label text is hidden to save space
  • Filter icon is colorized based on selected state (blue for Running, green for Completed, red for Error, white for Stopped/All)
  • Refresh button remains visible at all times
