feat: refactor parsing and scanning logic for test files

- Updated `parseFilename` to `parseTargetFilename` and modified its return structure to include `test_id` instead of `file_id`.
- Introduced `parseResultFilename` to extract `test_id` and `device` from result file names.
- Enhanced `fullScan` to separately handle target and results directories, improving clarity and functionality.
- Updated database interactions to use `test_id` instead of `file_id` across various modules.
- Added a new `/rescan` endpoint to trigger a full scan of target and results directories.
- Improved logging and error handling throughout the scanning process.
- Introduced `parseTputRssi` to extract throughput and RSSI data from log files.
