Develop a professional, lightweight native Android application named "Anas SMS Reader" designed for reliable automatic detection and confirmation of mobile financial service payments in Bangladesh (bKash, Nagad, Rocket, Upay).

Core Requirements:
- On first launch, gracefully request and handle the following runtime permissions: RECEIVE_SMS, READ_SMS
- Implement a foreground service with a persistent notification titled "Anas SMS Reader Active" and description "Monitoring for payment SMS - Do not close" to ensure reliable background operation and prevent the app from being killed by the system
- Continuously listen for incoming SMS messages in the background using a BroadcastReceiver
- Filter incoming SMS: Process only messages where the sender address contains keywords like "BKASH", "NAGAD", "ROCKET", "UPAY" (case-insensitive)
- For matching SMS:
  - Capture the sender phone number and full message body
  - Automatically parse the message for:
    - Payment amount: Search for patterns such as "Tk ", "BDT ", "Taka " followed by numeric value (e.g., "Tk 500.00" → "500")
    - Transaction ID (trxId): Search for patterns such as "TrxID ", "Trx ID ", "Transaction ID ", "Ref " followed by alphanumeric code (e.g., "TrxID ABC123XYZ" → "ABC123XYZ")
  - Immediately send an HTTP POST request to the fixed webhook URL: https://jleugjmibejzobcsnwmu.supabase.co/functions/v1/sms-confirm
  - Request headers: Content-Type = application/json (no API key required)
  - JSON payload:
    {
      "sender": "<sender_phone_number>",
      "message": "<full_sms_message_body>",
      "amount": "<extracted_amount_or_empty_string_if_not_found>",
      "trxId": "<extracted_trxId_or_empty_string_if_not_found>"
    }
  - On successful response (200 OK): Display a system notification "Payment SMS detected & successfully confirmed!"
  - On failure (network error or non-200 response): Display a system notification "SMS received but failed to send to server - will retry"

User Interface (Minimal and Clean):
- Main screen with a prominent large button labeled "Start Service" / "Stop Service" (toggle based on current state)
- Status text label showing "Service Running" (green) or "Service Stopped" (red)
- Scrollable log list displaying the last 5 processed SMS messages (for debugging and transparency, format: "From: sender | Amount: X | TrxID: Y | Time: HH:MM")

Additional Best Practices:
- Battery optimization: Use efficient parsing and minimal network calls
- Error handling: Log errors locally and retry failed webhook posts up to 3 times
- Security: Do not store any sensitive data; all processing in memory
- Compatibility: Target Android 8.0 (API 26) and above for modern device support
- Generate a production-ready, signed APK suitable for sideloading on dedicated devices

Prioritize reliability for background execution on real devices (e.g., Xiaomi, Samsung with aggressive battery management).
