Make it easier to refactor in the future.

Anything Else?

Found out that fastapi does redirecting /xxx to /xxx/ and vice versa.

AI Summary (optional)

This pull request implements several improvements and additions to the FastAPI backend project, focusing on API conventions, endpoint consistency, enhanced testing, and improved documentation. The most significant changes are the enforcement of no trailing slashes on collection endpoints, the addition of comprehensive end-to-end and database verification tests, and the introduction of API usage documentation and examples.

API Consistency and Conventions

• Enforced no trailing slashes on collection endpoints by updating all relevant route decorators in person.py, country.py, and continent.py to use paths without a trailing slash (e.g., /persons instead of /persons/). This ensures canonical URLs and consistent redirect behavior. [1] [2] [3] [4]
• Added a new "API Conventions" section to the README.md outlining route, sort, and filter syntax conventions for the API.

Testing Enhancements

• Added comprehensive end-to-end API tests in test_e2e.py covering CRUD flows, error handling, pagination, sorting, and cross-entity relationships, with database verification for persisted data.
• Updated existing API tests for persons, countries, and continents to verify that API responses match the database state, improving test reliability and coverage. [1] [2] [3] [4] [5]

Documentation and Developer Experience

• Added a new http/api.http file with example HTTP requests for all major API endpoints, facilitating manual testing and onboarding.
• Introduced a http-client.env.json file to support environment variable configuration for HTTP client tools.

Test Infrastructure

• Simplified and improved the health check test in tests/test_main.py by using the client fixture.

These changes collectively improve the API's usability, maintainability, and test coverage.

Pull request overview

This PR adds end-to-end API tests plus JetBrains HTTP client request files to make it easier to validate and refactor the FastAPI endpoints while preserving current behavior.

Changes:

• Enhanced existing API tests to cross-check API responses against database state via db_session.
• Added http/api.http and http/http-client.env.json to support manual API calls via JetBrains HTTP client.
