The platform no longer sells SMS. Each café saves its OWN Kavenegar API
key + sender line (new Cafes columns + migration) and campaigns are sent
and billed through that account.
Backend:
- GET/PUT /sms/settings (Manager/Owner; key echoed masked, verified
against the provider before saving)
- campaign + balance use the café's credentials; SMS_NOT_CONFIGURED
error when missing; plan-tier SMS gating removed everywhere
(PlanLimitChecker, SmsMarketingService, billing status)
- platform Kavenegar config stays ONLY for login OTPs (env/DB)
- design-time DbContext factory so `dotnet ef migrations add` works
without booting the host
Dashboard:
- SMS screen: provider-settings card, not-configured callout, campaign
form disabled until configured; quota bar removed (usage stays as info)
- subscription screen + plan comparison no longer show SMS limits
Admin panel:
- Kavenegar/SMS section removed from integrations (request field now
optional; stored OTP config untouched)
- SMS limit field removed from the plan editor
- nav label "درگاه و پیامک" → "درگاه پرداخت و AI"
fa/en/ar translations. 86 tests pass; all tsc clean.

Before, buying a plan immediately switched the tier and stacked the duration.
Now a purchase made while the café still has paid coverage is QUEUED to start
when the current coverage ends, and the owner can cancel a queued one.
Model:
- SubscriptionPayment gains EffectiveFrom/EffectiveTo; status gains Scheduled
(paid, queued) and Cancelled. EF migration AddSubscriptionScheduling (nullable).
BillingService:
- On payment completion, compute coverage end (latest of active expiry + furthest
queued period). If it is in the future → Scheduled (queued, café tier/expiry
untouched); else activate immediately as before. Periods chain correctly.
- GetStatusAsync lazily promotes any due queued period to active, and returns the
queue (QueuedPlans).
- CancelQueuedAsync cancels a Scheduled period (owner-only) and re-packs the queue
so later periods slide earlier. Active prepaid plan is never cut short; no
automatic refund (manual, per product decision).
- Confirmation SMS distinguishes "activated until X" vs "queued, starts X".
API: BillingStatusDto.QueuedPlans + DELETE /api/billing/queued/{paymentId}.
Dashboard:
- Subscription screen shows a "Queued subscriptions" card (tier, window, cancel
with confirm).
- Checkout shows "you already have an active subscription — this will start on
{date}" when the café is still covered.
- i18n fa/en/ar.
81 API tests pass; dashboard typechecks.
