feat: replace action row with a FAB

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
