kamilkrzywda 396702b9da feat(#52): dynamic scenario client (form → review → finalize) + e2e
Additive 'Create scenario' path (v0.31): the home screen's create-scenario
card opens a ScenarioForm (pick one of 3 light era templates + a free-text
description + an editable, era-prefilled start year) whose 'Generate world'
posts the draft request; the CheckpointReview screen shows the generated
world (per-nation stats/territory/relations + backstory) and the advisor's
checkpoint list as an approve/remove checklist, then the player picks a
nation to lead and finalizes into a saved, playable game. Both LLM steps ride
the scenario client (deterministic stub under LLM_STUB=1); a failure toasts
and stays on the current screen. The turn stub and static presets are
untouched. New e2e covers the full deterministic flow (near-future 2035,
remove checkpoint 3, lead Boreas, finalize, one empty jump) and the 3-template
manifest.
