FE-32: Production Build Hardening (Env Validation + Safe Defaults)

[Cedarich]

Complexity: 100 points
Summary
Prevent production-only failures by validating required environment variables and adding safe defaults for non-critical settings.
Tasks

• Implement startup-time environment validation with clear error output.
• Ensure no secrets are bundled into the client build.
• Add a dedicated “Misconfiguration” screen for missing critical config.
• Add CI checks that fail builds when required env is missing.
  Acceptance Criteria
• Builds fail fast when critical env vars are missing.
• No secrets appear in the client bundle.
• Misconfiguration states are obvious and actionable.
