houseme 6f05a740b3 refactor(ecstore): extract the shared io_uring read preamble (backlog#1145) (#4696)
`pread_uring` and `pread_uring_direct` accumulated across seven rounds
(#4632/#4635/#4645/#4649/#4653/#4658/#4662) and each carried its own copy of
the same open preamble: resolve the bucket path, run the volume access check,
resolve the object path, and check the path length. The only real difference
is what happens after — one opens buffered and errors as `DiskError`, the
other opens `O_DIRECT` and errors as `DirectOpenError` so it can latch an
O_DIRECT refusal.

Extract that shared sequence into `resolve_uring_object_path`, a blocking
helper called inside both `spawn_blocking` closures. Each caller keeps exactly
what differs — its open flags, its error type, its metadata/bounds/align
handling — and no longer restates the resolution. No behavior change: the same
checks run in the same order and produce the same errors (the O_DIRECT path
still maps them through `DirectOpenError::Disk`).

Net -12 lines. Verified on a real Linux host (16-core, real io_uring):
clippy -p rustfs-ecstore --all-targets -D warnings clean; disk::local tests
144 passed, 0 failed — including the io_uring, O_DIRECT, fd-cache, and
page-cache-reclaim cases that exercise both read paths.
