When changing library in circ/set-library.pl, desk and register values
were not being properly cleared from the session. This caused stale
desk/register data from the previous library to persist, resulting in:
- Incorrect cashup displays showing wrong library's register
- POS defaulting to registers from different libraries
- Session state inconsistent with visual UI
Three issues fixed:
1. Template: Changed register "None" option ID from "set-library-noregister"
to "noregister" to match JavaScript expectations (consistent with desk handling)
2. Desk logic: Changed condition to use defined() and explicitly clear session
when "No desk" is selected
3. Register logic: Added session clearing when "No register" is selected and
fixed condition to handle empty initial state
Test plan:
1. Select Library A with Register 5
2. Change to Library B without selecting a register
3. Verify register is cleared from session (check POS page)
4. Repeat for desk selection
5. Verify explicit "-- None --" selection clears session values
