Fix transitional icons and selection highlighting visibility

Resolved issues with transitional service icons not being properly visible:

- Removed 3-second timeout that was clearing pending transitions prematurely
- Fixed selection highlighting disappearing when transitional icons appeared
- Implemented conditional coloring for transitional icons:
  - Blue when service is not selected
  - Dark background color when service is selected (for visibility against blue selection)
- Transitions now persist until actual service status changes occur

Both selection highlighting and transitional icons are now visible simultaneously.
