Address bugs in numeric autofill

[martha]

Description

Summary of changes:

• In NumberInput, when triggering the onChange handler, pass the sourceInfo to indicate whether this event was triggered by a user or a system-generated change like autofill.
  • Why this is necessary for NumberInput specifically: NumberInput uses the react NumericFormat component internally, which calls onValueChange anytime the value changes.
  • That was causing the RHF state to mark the form field as "dirty" even when it had been autofilled. Whereas, normal autofill explicitly set showDirty: false:

hmis-frontend/src/modules/form/hooks/rhf/useDynamicFieldAutofillSync.tsx

Lines 17 to 27 in 79654b9

	useEffect(() => {
	// Don't autofill this field if it's been edited (i.e. is dirty)
	// for example, we automatically set the radio choice for Income Source to true if any of the income fields are non-zero
	if (isDirty && userEditable) return;
	if (!autofillValue) return;
	// Don't autofill if the value is already set
	if (isEqual(autofillValue.value, getValues(linkId))) return;
	setValue(linkId, autofillValue.value, { shouldDirty: false });
	}, [autofillValue, linkId, getValues, setValue, isDirty, userEditable]);

• Expand the existing autofill behavior to clear an autofilled value when the dependent item changes. This was previously in place only for readonly autofilled items. This PR proposes to expand that behavior to user-editable autofilled items, which seems more intuitive. Please let me know if you think there's a side effect I may be missing.
