Initial commit: JCD3198 second HDMI driver setup for Fedora

Enables the MCT T6 USB Station (0711:5601) chip on the J5 Create JCD3198
dock, which drives the 4K30 HDMI port with no native Linux kernel driver.

Stack: EVDI 1.14.16 (kernel module + libevdi) → t6evdi userspace daemon
(mobilepixels-linux-driver, patched for EVDI 1.14 API) → MCT T6 over USB.

Includes DKMS registration for evdi.ko (auto-rebuilds on kernel updates)
and a Mutter D-Bus layout script that restores monitor positions by serial
number after each daemon restart, working around the incrementing DVI-I-N
connector name assigned by EVDI on every reconnect.
