centralize API base selection and environment-aware fetching

[grantfox-oss]

frontend code duplicates base URL logic in many files (lib/api.ts, admin components, settings pages). Centralize and type the base API URL to avoid inconsistent environments.

• Impacted files: app/frontend/src/lib/api.ts, app/frontend/src/app/settings/developer/page.tsx, app/frontend/src/components/admin/AuditLogs.tsx, app/frontend/src/components/admin/FeatureFlags.tsx, app/frontend/src/lib/errorReporter.ts, `app/frontend/next.config.ts
