fix: remove frappe.db.commit() from OnSite WIP server script

Frappe v16's server script sandbox does not allow explicit commits —
the framework manages the transaction automatically after the event
handler runs. Calling frappe.db.commit() inside a DocType Event script
throws AttributeError: module has no attribute 'commit'.

Also adds fix_server_script_commit.py to patch already-deployed instances.
