Code-review fixes on the Authentik/budget/Resend work:
- UpsertForwardUser: avoid 500 lockout on username UNIQUE collision and
on the concurrent first-login race; normalize emails (lower+trim) so
case variants don't create duplicate accounts.
- Centralize email management in Authentik: when forward-auth mode is on,
email is read-only in Veola for every user (not just forward rows);
pure-local deployments keep editable email for Resend.
- Fail closed on per-user isolation: ownedItem rejects uid==0/orphaned
items; dashboard and global results error on a userless request.
- Budget accuracy: count Apify usage only after a successful run, and
count the billed Test Apify run.
- Efficiency: resolve the deal-email recipient once per poll; build the
settings page once in PostEmailPrefs.
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.
