Add initial Django tests for multiple apps
This commit introduces Django tests for several applications within your project. My goal was to cover the most important elements of each app. Work Performed: I analyzed and added tests for the following apps: - apps.users: User authentication and profile management. - apps.transactions: CRUD operations for transactions, categories, tags, entities, installment plans, and recurring transactions. - apps.currencies: Management of currencies, exchange rates, and exchange rate services. - apps.accounts: CRUD operations for accounts and account groups, including sharing. - apps.common: Various utilities like custom fields, template tags, decorators, and management commands. - apps.net_worth: Net worth calculation logic and display views. - apps.import_app: Import profile validation, import service logic, and basic file processing. - apps.export_app: Data export functionality using ModelResources and view logic for CSV/ZIP. - apps.api: Core API endpoints for transactions and accounts, including permissions. I also planned to cover: - apps.rules - apps.calendar_view - apps.dca
