Update project template and CI/docs tooling

[AndrewSazonov]

Refreshes the project against the latest EasyScience template changes, including Pixi platform metadata, CI workflow updates, docs/mkdocstrings configuration, Ruff/nbQA settings, and formatting cleanup. Also fixes the logger context manager annotation/docstring mismatch so pixi run fix and pixi run check remain consistent.
