- Fix logToDb() to use actual database schema: 'date' and 'message' columns
- Change INSERT query from non-existent 'timestamp, level' to existing 'date, message'
- Change DELETE cleanup to use 'date' column instead of 'timestamp'
- Embed log level in message text as '[LEVEL] message' instead of separate column
- Use toDateString() format to match schema instead of toISOString()
Resolves: "table logs has no column named timestamp" infinite error loop
Critical: Enables Electron app initialization by matching code to existing schema
Impact: Stops database logging from crashing and allows normal app startup
