feat(scene): honour the last DimStyle fields end-to-end

Tessellation and DIMBASELINE pick up the few DimStyle fields that were
still hard-coded or ignored:

- DIMTMOVE = 1 draws a connector segment from the dim-line anchor to the
  saved text_middle_point when the text has been moved
- Leader arrows are resolved via the leader's DIMSTYLE → DIMLDRBLK; the
  shape (closed-filled / open / dot / tick / …) is drawn through the same
  arrow emitter the dim path uses, including fill_tris for filled blocks
- DIMBASELINE picks up DIMDLI from the active DimStyle instead of the
  hard-coded 1.5 increment
- DIMTOFL / DIMTIX / DIMATFIT / DIMUPT / DIMTXTDIRECTION are read so the
  fields round-trip on save; their effect is at dim creation, not render,
  so they're acknowledged with a no-op block
