Add Authentik SSO, budget visibility, Resend email, 12h item default

Opens Veola up to more users (Parodia's Authentik) and makes Apify spend visible to everyone. - Auth: Traefik forward-auth (trust X-Authentik-* headers only from trusted_proxies CIDRs, keyed by email, role synced from admin_group), keeping local password login as break-glass. New [auth] config, CaptureDirectIP + ForwardAuth middleware, deploy/authentik-forward-auth.md. - Budget: count every Apify run (apify_api_usage table) and show calls + estimated cost to all users on the dashboard, with an optional monthly-budget bar. New [budget] config + settings. - Email: Resend client for opt-in deal alerts and a weekly digest (Mon 09:00). Per-user email + toggles on Settings. New [resend] config. - Defaults: new items default to a 12-hour poll interval to cut spend. users table gains email/auth_source/email-pref columns (migrated in place). go build/vet/test green; boots and migrates cleanly.
