* fix(volume): don't panic on read when needle map is nil
A failed CommitCompact reload (and #9335's new error path for a
remote-tiered volume with a stray .vif but no .idx) leaves v.nm == nil
on a volume that's still in the store. readNeedle / readNeedleDataInto
dereferenced v.nm with no guard, so the next GET segfaulted the
http handler instead of returning an error the client could retry on
another replica.
Add the same v.nm == nil check the other Volume accessors already use,
including the slow-read inner loop where the lock is released between
iterations and a failed reload can race in.
Fixes#9339.
* match rust nm-nil read behavior; trim comments
seaweed-volume's read_needle_with_option / re_lookup_needle_data_offset
already lift Option<NeedleMap> through ok_or(NotFound). Use ErrorNotFound
on the Go side too instead of a generic 500-mapped error so both volume
servers respond identically when v.nm is nil.
* log once when reads hit nil needle map
ErrorNotFound alone hides the real cause: a half-loaded volume just
returns 404s and the operator has nothing to grep for. Add a once-per-
volume Errorf on the nil path, reset on successful load. Mirror the
same in seaweed-volume via nm_or_not_found().
* trim comments
* drop once-flag, log inline on every nil-nm read
* fix: close volumes and EC shards in tests to prevent Windows cleanup failures
On Windows, t.TempDir() cleanup fails when test files are still open
because Windows enforces mandatory file locking. Add defer v.Close(),
defer store.Close(), and EC volume cleanup to ensure all file handles
are released before temp directory removal.

* refactor: extract closeEcVolumes helper to reduce duplication
Address code review feedback by extracting the repeated EC volume
cleanup loop into a closeEcVolumes() helper function.
