test(e2e): drop 187 no-op serial markers from the three densest e2e suites (#6209)

test(e2e): drop no-op serial markers from the three densest e2e suites

serial_test's #[serial] is an in-process mutex. cargo-nextest, this repo's
authoritative runner, executes every test in its own process, so the mutex is
never contended and the attribute is a documented no-op -- see the "Serial
execution & nextest profiles" section of docs/testing/README.md and the header
of .config/nextest.toml. Cross-process serialization is provided only by a
[test-groups] entry with max-threads = 1.

Remove 187 such markers (plus 3 now-unused imports) from the three
marker-densest modules of crates/e2e_test:

  multipart_auth_test.rs             85
  replication_extension_test.rs      68
  object_lock/object_lock_test.rs    34

None of these modules is covered by any [test-groups] entry, so the markers
were carrying no isolation for any lane. Every test in all three files builds
its own server via RustFSTestEnvironment::new(), which gives a UUID temp dir
and a uniquely allocated port -- the .config/nextest.toml comment on
replication_extension_test already states this explicitly ("parallel-safe by
construction"). No test mutates process env, binds a fixed port, or touches
process-global state, so nothing here needed temp_env or a test-group instead.

Pure deletion: 190 lines removed, 0 added, no test renamed, no behaviour
changed. serial_test stays in Cargo.toml -- 338 markers across 90 other files
in the crate still use it.

Refs: backlog#1846 (T1).
