Zhengchao An d7b19131d8 fix(ecstore): read the persisted SSE-C nonce in the GET decrypt resolver (unbreaks S3 CI) (#4612)
fix(ecstore): read the persisted SSE-C nonce in the GET decrypt resolver

#4576 moved SSE-C encryption to a random per-encryption nonce persisted
in object metadata and taught the rustfs-layer decrypt resolver to read
it back — but the byte-level GET decryption resolves its material in
crates/ecstore object_api/readers.rs, a duplicated twin that still
recomputed the deterministic legacy nonce. Encrypt with the random
nonce, decrypt with the deterministic one: the first AEAD block fails
and every SSE-C GET aborts its body after the response headers
(IncompleteRead(0 bytes) on clients; all 8 SSE-C cases in the
implemented s3-tests whitelist), which is what has been driving the
"S3 Implemented Tests" CI job into its 60-minute timeout since
2026-07-09.

Resolve the base nonce like the encrypt side: prefer the persisted IV
(x-rustfs-encryption-iv, then the case-insensitive MinIO interop key),
fall back to the deterministic nonce only for legacy objects with no
stored IV or an undecodable value. Full implemented s3-tests whitelist
is back to 451 passed / 0 failed against the fixed binary.
