Add DisposableEmailService that fetches ~72k disposable email domains
from github.com/disposable/disposable-email-domains into an in-memory
frozenset with 24h auto-refresh via asyncio background task.
Integrated into three email entry points in cabinet auth routes:
- POST /email/register (link email to Telegram account)
- POST /email/register/standalone (standalone email registration)
- POST /email/change (change existing email)
Controlled by DISPOSABLE_EMAIL_CHECK_ENABLED setting (default: true).
Falls back to allowing all emails if domain list fetch fails.
New setting allows granular control over trial availability:
- none: trial available for all (default)
- email: trial disabled for email users
- telegram: trial disabled for telegram users
- all: trial disabled for everyone
Enforced in bot handlers, cabinet API, and miniapp routes.
Automatically appears in admin panel as dropdown via CHOICES.
Add BlacklistMiddleware for aiogram that blocks all message/callback/pre_checkout
from blacklisted users globally. Add blacklist check to cabinet API dependency.
Fix case-insensitive username matching. Remove 10 redundant manual checks from handlers.
