Fix Table user kwarg crash and single-source version

- Remove user=request.user from typed tab table instantiation;
  django_tables2.Table does not accept this kwarg and NetBox 4.5.4
  passes it through, causing TypeError. Per-user preferences are
  already applied by table.configure(request) called immediately after.
- Read plugin version from package metadata (importlib.metadata) so
  it is defined only in pyproject.toml, not duplicated in __init__.py.
