Handle foreign keys and indices properly in SQLite and add e2e tests

This patch resolves issues with `change_column` and `drop_column` which previously caused duplicate or missing indices and foreign keys. To prevent future regressions and help debugging,
a new e2e-test pipeline has been added to the project and the CI. Documentation for running the tests has been added to the README.

End-to-end tests currently support MySQL, PostgreSQL, and SQLite and do not yet cover other SQL dialects.

During review, please help ensure that the SQL fixtures are not missing something :)

Closes #92
