chore(release): Bumped to Version 15.118.3

## [15.118.3](https://github.com/frappe/erpnext/compare/v15.118.2...v15.118.3) (2026-07-30)

### Bug Fixes

* **italy:** skip e-invoicing for opening invoices ([4f07e25](4f07e2503b))
* **stock:** keep manufactured item rate at zero when inputs are free  (backport [#57334](https://github.com/frappe/erpnext/issues/57334)) ([#57512](https://github.com/frappe/erpnext/issues/57512)) ([ade3f79](ade3f791a4))
