Fully implement Kavenegar SMS support
Core changes:
- ISmsService: add SendBulkAsync (batches of 200) + GetAccountInfoAsync
- KavenegarSmsService: POST requests, sender number config, bulk send
via comma-separated receptors, account balance, full error code mapping
(HTTP 400-432), enabled-flag check before any send
- SmsMarketingService: replaced per-recipient loop with SendBulkAsync
- SmsController: new GET /sms/balance endpoint returns Kavenegar credit
- SmsDtos: SmsBalanceDto
- IntegrationDtos + PlatformIntegrationService: SenderNumber field
- appsettings.json + docker-compose: Kavenegar__SenderNumber = 90005671
Dashboard:
- sms-screen: char counter, SMS parts indicator (Persian 70/67 chars,
Latin 160/153), account balance card, sender line display, result banner
