Get Pricing

Global billing constants + offer config for the AutoGTM UI.

Static — no DB access. Returns the same shape as autogtm-back's public /api/pricing-config so the dashboard slider and the paywall calculator share one source of truth (api/app_auto_gtm/projections.py).

Caller email is threaded through so per-account UI-floor overrides (projections.SPECIAL_DAILY_MIN_USD) can lower the slider min for specific customers without touching the global anchor.
