Add "lift kit" for Campaign 2 bus

Campaign 2's larger wheels now hang further under the chassis via a new `wheelRestOffsetY` theme knob (42 vs 34 design units), making the bus visibly sit taller. The wishbone anchor and initial wheel position derive from this per-campaign offset, so both size and mount point stay correctly centered on the axle line.

- Add `BUS.wheelRestOffsetY2` in config
- Expose `wheelRestOffsetY` in theme `bus` blocks (default = campaign 1)
- Use themed offset in Bus constructor for anchor and wheel placement
- Update docs/comments to explain the lift-kit behavior
