Plant view: inline optical QC station at every press

User, 18 Oct 2026: add the new inline inspection machine to the factory.

- Fleet calculator, isometric plant view: qcStation() draws the concept
  station (1.9 x 0.65 x 1.5 m: aluminium conveyor table with the two rim
  belts, light-tight tunnel, stack light, record on the infeed, reject
  bin) in front of the operator in every Duplex cell (after the trimmer)
  and at the unload side of every Classic, in the hall and in phase 2;
  own ids qc-duplex-n / qc-classic-n with tooltips from
  inline-optical-qc.md (Classic hand-off open with Newbilt). Cell floor
  extended to take the bin.
- The finishing block's end-of-line optical station becomes the release
  inspection: the same station measuring cooled samples (records settle
  ~24 h); corridor, block and conveyor tooltips reworded.
- Machine park schematic: a QC bar in every Duplex cell and Classic, an
  "inline QC" legend entry; the legend moved to the bottom of the hall
  box (it collided with the hall heading).
- Docs: inline-optical-qc.md (release station location, plant view),
  site-candidates.md block ground floor, crane-workshop-tours.md tour
  stop 6.

Checks: node --check on all scripts; pw_bp_calc.py 0 fails;
pw_iso_view_check.py OK; every data-id has info at all presets, levels
and rotations; legend clear of cells and heading up to 30M records;
zoomed shots in both themes and two rotations. GF node count at the full
preset 2,523 (was 2,388), 8M records ~2,980; rebuild under 60 ms.
