[FIX] core: werkzeug 3.1 compatibility

xmo-odoo · xmo-odoo · commit ed2f299a6960 · 2025-07-16T13:18:10.000+02:00
Werkzeug 3.0 deprecated `werkzeug.__version__` and 3.1 removed it.

Trixie bundles werkzeug 3.1.3. So use `importlib.metadata.version` to
retrieve the package's version. It was made final (non-provisional) in
Python 3.10 which is the minver for odoo 17 so no need for a
conditional.

Also remove the unnecessary fallback in `test_misc`.
