fix: Adapt versioning scheme to Home Assistant and switch to uv (#896)

Home Assistant expects versioning always increases numbers. Add
a date component to the development version to comply with this
expectation. The scheme is now 0.0.0.dev<date><hash>.

Use uv for creating and managing the virtual environment for developement.
This enourmously speeds up dependency updates. For this change
dependency requirements are now solely handled in pyproject.toml.
requirements.tx and requirements-dev.txt are deleted.
