Add BOM cable length sub-grouping

Per organized-ideas.md §7: cables of the same type sharing the same length
now get their own subtotal (count + total length + cost), revealed by
expanding that cable type's row rather than only showing one blended total.
Closes out the last open item in §7 — cost input, per-diagram override, and
the grand total were already in place.

- domain/bom.ts: computeBom groups each cable type's connections by
  distance too (a separate bucket for connections with no length entered),
  sorted shortest first.
- BomPanel: a chevron toggles the breakdown, only shown when a cable type
  actually has more than one distinct length group (nothing to reveal
  otherwise).

Verified: tsc -b and oxlint clean. No backend involved.
