* fix: EC UI template error when viewing shard details
Fixed field name mismatch in volume.html where it was using .ShardDetails
instead of .Shards. Added a robust type conversion wrapper in templates.go
to handle int64 to uint64 conversion for bytesToHumanReadable.
Added regression test to ensure future stability.
* refactor: improve bytesToHumanReadable and test robustness
- Handled more integer types (uint32, int32, uint) in bytesToHumanReadable.
- Improved volume_test.go to verify both shards are formatted correctly.
* refactor: add bounds checking to bytesToHumanReadable
Added checks for negative values in signed integer types to avoid incorrect
formatting when converting to uint64.
Addressed feedback from coderabbitai.
