fix: mount SD kaart dynamisch via udev %k i.p.v. hardcoded UUID

Browse source 
dashcam-transfer-mount.sh mountte altijd /dev/disk/by-uuid/00D3-7715.
Een geherformatteerde of andere kaart heeft een ander filesystem UUID,
waardoor de mount faalde (TRIGGER ERROR) en de transfer nooit startte.

De udev rule geeft nu het kernel device (%k) door; de helper mount dat
device dynamisch. Werkt ongeacht het FS-UUID van de kaart.
