Introduced tables for devices, accounts, and transactions in the schema, along with associated models. Implemented DAO methods for CRUD operations, including upsert functionality for accounts and deduplication for transactions. These changes enable structured management of account and transaction data.
Updated all SQL queries and bindings to replace camelCase field names (e.g., `updateTime`, `lastScan`) with snake_case equivalents (e.g., `update_time`). Ensures uniformity across database schema and codebase.
Ensures that the app_data.db file is copied to the build directory alongside other resources. This is necessary to guarantee all required files are available for the application to function correctly.
Added SQLite database support for managing device information and common data. Implemented DAOs for handling device and common data operations, such as inserting/updating devices and tracking the last scan time. Enhanced `DeviceScreener` to read device info, update database records, and take screenshots.
Added a background worker using QThread for device screening and integrated Tesseract OCR for text recognition from images. Refactored project structure, updated CMakeLists for Tesseract support, and adjusted .gitignore for build files.
