Expose Scanner Status to Other Processes

[vgarcia007]

Currently, there's no straightforward method for other scripts (such as the API) to retrieve the scanner's status or progress.

The main Python script should expose this status in a way that can be easily accessed. Possible solutions include:

• A simple "status file" in a temporary location that other scripts can check.
• Alternatively, using a Redis container to store statuses. However, this may be overkill.

The scanner needs to report on three possible states:

{
  "scan": true/false,       // indicates if a scan is in progress
  "waiting": true/false,    // indicates if it's waiting for rear pages
  "ocr": true/false         // indicates if OCR processing is pending
}
