Fix laptop card slot not being checked for software access (#19300)

Browse Source 
can_run() only checked the user's worn/held ID via GetIdCard(), ignoring any
card inserted into the computer's RFID card slot. This caused access-locked
software to always show an RFID error for users relying on a slotted card.

Three fixes:
- can_run(): add explicit_card param; resolution order is explicit_card,
  then user.GetIdCard(), then computer.card_slot.stored_card
- run_program(): set TM.using_access from the slotted card when present,
  falling back to user.GetAccess()
- ntdownloader.dm: pass my_computer.card_slot.stored_card to can_run() so
  the software download list respects the slotted card
