Compass Config: Rotation of Compass using combo boxes

I think we should raise an enhancement to do this using a three combo boxes and some rotated graphics to help. (same idea can be used for board orientation)

| Roll | Pitch | Yaw |
| 0 |
| 45 |
| 90 |
|135 |
|180 |
|225 |
|270 |
|315 |

Review the existing Compass Config UI and any current board-orientation handling first; the issue names no files, tests, or entry points. Clarify the design for three Roll, Pitch, and Yaw combo boxes using the listed angles and rotated graphics, with completion covering the proposed board-orientation reuse.
