Screen dimming: add a 15% idle-dim level

Browse source 
Add SCREEN_DIM_15 (Off / 100 / 50 / 30 / 15). The value now needs 3 bits, so
repurpose the spare BIT_UNUSED_2 as BIT_SCREEN_DIM_2; existing codeplugs (bit 2
clear) keep their level, no reset.

## Unreleased
- **Screen dimming:** added a **15%** idle-dim level (Off / 100 / 50 / 30 / 15).
- **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.
