* [manunal] Gridstore page use universal IO
* fmt
* Apply review feedback for universal IO gridstore pages (#8230)
* Apply review feedback from PR #8223
- Use `super::Result` import in mmap.rs instead of fully-qualified `crate::universal_io::Result`
- Restructure ValuePointer destructuring in get_value and delete_value to
first match Some(pointer), then destructure separately
* Replace Either<E, GridstoreError> with E: From<GridstoreError> in Gridstore::iter
Use a trait bound instead of Either to combine callback and gridstore
errors, allowing `?` to work directly on GridstoreError. This simplifies
callers by removing Either matching and io::Error conversion workarounds.
