chore(main): Migrate to uv

[CarliJoy]

This PR removes poetry and replaces it with uv.

Also:

• remove not required pyproject.toml/requirement.txt/setup.py files -> everything is kept in one pyproject.toml and common lock file
• remove not required Dockerfile for docs. uv run just works fine here
• keep license file in release (it is good)

closes #957

Note: This PR is based on #920 in order to have a working CI/CD

Review notes:

• Locally build packages once in main and once in this branch.
• Compare the results.
• Test make endpoints
