唐小鸭 f51b06f0ae perf(ecstore): enable encrypted range part-seek by default (#6598)
Range GETs on encrypted objects read the whole ciphertext from offset 0
and discarded the decrypted prefix, because the part-boundary seek
shipped behind RUSTFS_ENCRYPTED_RANGE_SEEK defaulted to false
(backlog#1316 Phase A).

Flip the default to true. Safety rests on the marker chain: MPUs created
without a candidate layout marker never become seek-eligible,
CompleteMultipartUpload promotes the candidate to the quorum marker only
after revalidating it against the object's data_dir under the uploadId
write lock, and reads seek only when the quorum marker matches the
current data_dir. Single-part, compressed and markerless objects keep
the full-read path; RUSTFS_ENCRYPTED_RANGE_SEEK=false remains the kill
switch.

The stale default-off regression test becomes
test_legacy_range_seek_defaults_enabled: the unset-env default must
match the explicit opt-in plan, seek past the leading parts, and not
span the whole ciphertext.
