mikkeli 0b3783dac0 BOM: add Waveshare UPS Power Module (C)
15-19 V in, 3S 21700 pass-through UPS with an INA219 that the car unit
sees on I2C bus 7 at 0x41 (read-only check: 12.34 V, idle). Bench test
held the Orin >=20 s across a supply swap. Notes the 20 V PD caveat and
the intended ignition-off shutdown via battery current direction.
