feat: add MongoDB database as a part of the CLI

[pythonhubdev]

Overview

Fixed MongoDB test failures in generated FastAPI projects. The test files were hardcoded for SQLAlchemy but failed when MongoDB was selected as the database type. Made all test-related templates conditional based on database_type to support both SQLAlchemy and MongoDB configurations.

Type of Change

• Bug fix

Scope / Affected Areas

• Developer tooling

Breaking Changes

• No

Public API Impact (Python SDK)

• New modules/classes/functions:
• Changed/removed APIs:
• Deprecations (timeline and migration path):

Testing & Verification

• Commands run locally:
  • task test (pytest)
  • task lint (ruff/pyright/mypy)
  • pre-commit run --all-files (optional)
• Added/updated tests: [ ] unit [ ] integration
• Key scenarios and edge cases:
  • Generated FastAPI projects with MongoDB database type now have working tests
  • SQLAlchemy projects continue to work as before
  • Both database types use appropriate connection patterns and fixtures

Documentation

• Notes:
  • MongoDB support in scaffoldr now includes proper test configuration

Environment / Config Changes

• New/changed env vars:
• Defaults and validation:
• Backwards compatible: [yes]

Checklist

• Code formatted and linted (ruff format/check)
• Type checks pass (pyright, mypy)
• No secrets/keys committed

Pull Request Overview

This PR fixes MongoDB test failures in generated FastAPI projects by making all test-related templates conditional based on the database_type parameter. Previously, test files were hardcoded for SQLAlchemy but failed when MongoDB was selected as the database type.

• Made all test templates conditionally render based on database_type (SQLAlchemy vs MongoDB)
• Added MongoDB-specific test configurations and fixtures
• Enhanced CLI testing script to include MongoDB test scenarios
