Steam and cooling, plant operation: show the launch plant (1 Duplex + 1 Classic)

User (October 2026): "launch plant should be 1x duplex system and 1x
classic". The calculator already did; these two pages did not.

- steam-cooling.html: default case is now "Launch plant" (D1-A, D1-B,
  Classic; B-1 and B-2; CH-1 and CH-2: 450 to 540 kg/h on 1,000 kg/h,
  391.5 kW on 500 kW). Other cases: Duplex first (commissioning), Second
  Duplex (growth option, five presses), One module down (launch plant
  with B-2 and CH-2 out). Idle boxes say "reserved position" / "growth
  option". Phasing table: launch plant, second Duplex, options;
  galvanics cooling is launch scope. Five-press figures labelled as the
  growth case or backbone sizing; chiller cost per the CSV 2-module row.
- plant-operation.html: the launch plant: Classic C2 removed everywhere
  (press, trimmer, routes, conveyor, lamps, texts), Classic re-centred;
  one PDPU (2 cells) as in total-investment; boilers 2 x 500 kg/h,
  chillers 2 x 250 kW; title arrivals scaled to three presses; phone
  legend in one column.
- Landing entries and README bullets for both pages.

Verified headless (Edge): skill checks pw_sc_check and pw_plant_check
with launch-plant expectations, 90-day runs, perf unchanged; 390 / 1024
/ 1440 px dark and light without page errors or overflow.
