Subject: [PATCH] Add sensor type 0x969 (HP ZBook Studio x360 G5, 138a:00ab)

The 138a:00ab USB ID is shared across HP machines but maps to different
sensor silicon. The EliteBook 840 G5 reports sensor type 0xd51; the ZBook
Studio x360 G5 reports 0x969. Both lack native SensorTypeInfo /
SensorCaptureProg entries, and empirically both work when aliased to the
0x199 capture profile -- the on-chip matcher accepts the resulting images.

Mirror the existing 0xd51 handling for 0x969:
- add 0x969 to line_update_type1_devices
- alias 0x969 -> 0x199 in open()
- accept the b[0]==3 finger interrupt when real_device_type is 0x969

Verified on an HP ZBook Studio x360 G5: init + calibration + enroll
(5 stages, enroll-completed) + verify (verify-match).
