Build: parameterize by platform, add DM-1701 (RT-84) target

Browse source 
./build-firmware.sh DM1701 builds OpenDM1701.bin with PLATFORM_RT84_DM1701 +
PLATFORM_VARIANT_DM1701 (vs PLATFORM_MDUV380). Same firmware source, same GCC 14
toolchain and codec placement. Not officially tested on DM-1701 hardware yet.

## Unreleased ## Unreleased
_Nothing yet._ - **DM-1701 build support** — the Docker build is now parameterized by platform;
`./build-firmware.sh DM1701` produces `OpenDM1701.bin` (Baofeng DM-1701 /
Retevis RT-84). Not officially tested yet.
