chore(cra): align CRA module to the dev/demo tenant + demo-customer seed script

CRA frontend pages hardcoded tenant 00000000-…-001 while IACE uses the dev
tenant 9282a473-… → a demo customer was split/invisible across modules. Align all
app/sdk/cra pages to 9282a473-… so the whole CRA<->IACE journey lives under ONE
tenant. Add scripts/seed_demo_customer.py: seeds CompanyProfile + IACE project
(components, hazards, mitigations) + CRA project (intake, scope-check, assessment
snapshot from faked repo findings + components + safety functions) — the source-
repo layer is faked so the full frontend is walkable once.
