fix(payments): enforce strict YooKassa webhook binding

Require payment_db_id for successful webhook processing and validate ownership. Precreate payment records for auto-renew and include payment_db_id in provider metadata. Ignore replayed succeeded webhooks. Also normalize empty Telegram webhook secret before set_webhook and request handler usage.
