fix(ui): let the per-user Internal Users edit form save sub-cent budgets

The same native step veto lived on the per-user edit form: its Max Budget
field renders through NumericalInput with step={0.01} inside an antd form
that never opted out of constraint validation, so typing 0.001 on a user
and pressing Save Changes did nothing at all; no request, no error, and the
detail view kept showing the previous budget.

The field now uses step="any" and the form carries noValidate, so antd's own
rules stay the only gate. The dead precision={2} prop went with it: it is an
antd InputNumber prop and NumericalInput renders a Tremor NumberInput, so it
only ever leaked to the DOM.
