Anatol Belski 264013b424 block: disk_file: Add DiskBackend dispatch enum ...

Introduce DiskBackend with two variants:
- Legacy: wraps Box<dyn async_io::DiskFile> for existing formats
- Next: wraps Box<dyn disk_file::AsyncFullDiskFile>

Methods return BlockResult, with DiskFileError converted up to
BlockError on the Legacy path. The Next path passes through
directly with zero conversion overhead.

This is a transitional type. Once all formats implement
AsyncFullDiskFile, DiskBackend and Legacy are removed and
callers hold Box<dyn AsyncFullDiskFile> directly.
