refactor(gfql/row): collapse duplicate ValueError in _gfql_resolve_token

Wave 4 finding D1 (SUGGESTION): the conditional at pipeline.py:2310 and
the raise at pipeline.py:2312 produce identical errors. After the
node-id branch (lines 2306-2309) returns, the only remaining outcome
is "unsupported token", regardless of edge_aliases membership — both
branches raised the same f-string. Collapsed to a single raise.
