[POS Orders] Enable pointOfSaleOrdersi2

[iamgabrielma]

Description

This PR sets pointOfSaleOrdersi2 to true, enabling Sales Channel as a filter option in production builds.

Testing information

• Run the app in release build configuration
• Go to the orders tab, tap on Filters, observe that the new Sales Channel filter appears as an option

---

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
