Replaces the single uaux-at-byte-0 broadcast (commit d209a47) with a
7-byte expanded telemetry frame. Bench capture on green car showed dual
0x210 frames colliding (DLC=8 simple + DLC=7 expanded) because Kyle's
flashed image had both AddSend sets active; standardising on the
expanded layout eliminates that ambiguity.
Byte layout:
byte 0 state (0=Off, 1=WaitStart, 2=Enable, 3=Activate, 4=Run, 5=Stop)
bytes 1-2 udc (V, gain=1)
bytes 3-4 idc (0.1A, gain=10)
byte 5 uaux (decivolts, gain=10) — 12V aux battery rail
byte 6 soc (%, gain=1)
byte 7 reserved
Consumed by stm32-hal-vcu Core/Src/main.c CHARGER_CAN_ID_OI_OBC_AUX
handler. The state byte enables future VCU_IsCharging integration via
state == 4 (Run) without requiring a second CAN ID.

Builds firmware on PR/push to main. Initializes libopencm3 and
libopeninv submodules then runs make. Uploads stm32_charger.bin
as a 30-day retained artifact.

Adds AddSend for Param::uaux at CAN ID 0x210, bit 0, length 8, gain=10.
Transmits 12V aux battery voltage in decivolts/0.1V steps (e.g. 125 = 12.5V).
VCU reads byte 0 of 0x210 for 12V battery protection logic per SKUDAK-448.
