Synchronous dbQueue.write blocks actor thread in NotificationService

[fatihkan]

Bug Description

In NotificationService.swift:34, synchronous dbQueue.write calls block the actor's cooperative thread pool. Under load (many notifications), this can starve other actors and cause UI freezes.

Location

CreedFlow/Sources/CreedFlow/Services/Notifications/NotificationService.swift:34

Severity

Critical — Blocks Swift concurrency thread pool, potential deadlock.

Steps to Fix

1. Use dbQueue.asyncWrite or wrap in Task.detached with a non-actor-isolated closure
2. Or move DB writes to a dedicated dispatch queue
