fix: update default EDID to enable audio support 

The previous default EDID did not advertise audio capabilities,
preventing HDMI audio capture from working. This update ensures
the JetKVM properly identifies itself to source devices and
enables audio capture out of the box.

Changes:
- Display identifies as "JetKVM HDMI" (manufacturer ID: JTK)
- Includes full audio support (2/6/8-channel LPCM, up to 192 kHz)
- Advertises all TC358743XBG capabilities (1080p60, YCbCr, Deep Color)

This allows HDMI audio to work by default without manual EDID
configuration.
