* fix(api): normalize non-object JSON bodies to empty dict in token PATCH
Valid non-dict JSON (e.g. [] or null) reaches payload.get(...) and
raises AttributeError. Normalize to {} so the route returns a controlled
response instead of an unhandled 500.
Fixes#3966
* test(api): add regression tests for PATCH with non-object JSON bodies
Covers array body ([]), null body, and normal object body as requested
in alteixeira20's review of #3976.
