fix(PWA): remove approval status field from expense claim form view

[fadilsiddique]

Before:

Employees can select approval status as draft, approved or rejected and save the form.

After:

Moved the approval status to excluded fields.

function getFilteredFields(fields) {
	// reduce noise from the form view by excluding unnecessary fields
	// eg: employee and other details can be fetched from the session user
	const excludeFields = [
		"naming_series",
		"task",
		"taxes_and_charges_sb",
		"advance_payments_sb",
		"approval_status"
	]
	const extraFields = [
		"employee",
		"employee_name",
		"department",
		"company",
		"remark",
		"is_paid",
		"mode_of_payment",
		"clearance_date",
	]

	if (!props.id) excludeFields.push(...extraFields)

	return fields.filter((field) => !excludeFields.includes(field.fieldname))
}
