Detailed Description

What a user gets from a NEW design: session start, Doublet, Ethalox (DEF-01..12 defaults).

The UI builds a new design through the backend's own sequence: a fresh session loads
configs/default.yaml, each dropdown is POST /api/config/switch (config_to_dict -> switch_config ->
PintleEngineConfig), and the Layer 1 "Run" on a pintle design switches to impinging the same way.
These tests build the design exactly so, and check it against numbers that do not come from this
codebase: CEA (rocketcea) and CoolProp, quoted with the conditions they were read at.
