* filer, volume server: return 416 when no requested range overlaps the content
* seaweed-volume: return 416 when no requested range overlaps the content
* server: check the range test error, use the request context, fix the no-overlap comment boundary
* fix(shell): correct volume.list -writable filter unit and comparison
* fix(shell): correct volume.list -writable filter unit and comparison
* chore(shell): fix typo in EC shard helper param names
* fix(shell): use exact match for volume.balance -racks/-nodes filter
The old strings.Contains-based filter quietly included any id that was a
substring of the user-supplied flag value (e.g. -racks=rack10 also matched
rack1). Replace it with an exact-match set parsed from the comma-separated
flag value, and add regression tests for both -racks and -nodes paths.
Also fix a small typo in the "remote storage" error returned by
maybeMoveOneVolume.

* refactor(shell): drop nil sentinel in splitCSVSet, use len() in callers
* fix: avoid reading upload body when writing JSON errors
* writeJson: drop unused JSONP branch
No in-tree caller uses ?callback=. Always serve application/json
with X-Content-Type-Options: nosniff.
* seaweed-volume: drop unused JSONP branch
Mirror Go: always serve application/json with
X-Content-Type-Options: nosniff.
* writeJson: drop unreachable StatusNotModified check
bodyAllowedForStatus already returns early for 304.
* test/volume_server: rename and rewrite JSONP test to assert callback is ignored
CI: /status?callback=myFunc now returns plain application/json
with X-Content-Type-Options: nosniff.
