Fix I2C addresses in TUI demo and device screen

Browse Source 
demo.py: hotplug mock used [0x08, 0x50, 0x51, 0x61], corrected to
[0x08, 0x10, 0x51] per hardware bus scan. 0x50 was never on the bus;
0x61 was speculative.

device.py: known device map had 0x60 "BCM3440 tuner" and 0x61
"ISL6421 LNB controller" — neither appears on the SkyWalker-1 I2C bus.
Replaced with 0x10 "Tuner / LNB controller" per confirmed scan.
