I'd like to work on upgrading the backend to support Appwrite v1.8.0, which introduces the new TablesDB API replacing the older Collections/Documents structure.

This update will ensure better compatibility with the latest SDKs, improve performance, and align the backend with the latest Appwrite architecture.
I’ve already reviewed the v1.8.0 release notes and migration guide, and I’m confident about handling the required changes.
Please assign this issue to me so I can start the migration and testing process.
