Monkey-patched _get_form missing max_part_size parameter from starlette 1.0.0

High Severity

Removing the starlette==0.41.2 constraint allows upgrade to starlette 1.0.0, but prepline_general/api/app.py monkey-patches Request._get_form with a signature that only accepts max_files and max_fields. Starlette 0.44.0 (PR #2815, Dec 2024) added max_part_size to _get_form's signature, and form() forwards it. At runtime, starlette 1.0.0's form() will call _get_form(max_files=..., max_fields=..., max_part_size=...), causing a TypeError on the patched version. This breaks all multipart form uploads — the API's core functionality.
