Stacks on #1522. Bumps the Oracle test client from 21.21.0.0.0 to 23ai (23.26.0.0.0), which matches the database server used in CI (gvenzl/oracle-free:23.x). 21c is an older innovation release, and the 23ai client may have fixed or changed the finiSqora cleanup path behind the exit hang.

The install script is now parameterized (oracle_version/oracle_build/oracle_dir/oracle_driver/oracle_so) so the next bump is a few lines.

Validation (local, Fedora 44): installed the client via the new script, started the compose oracle service, built with --features odbc-static, ran the suite as CI does (--test-threads=2, MALLOC_CHECK_=3, MALLOC_PERTURB_=10): 90 passed, 0 failed in ~16s, clean process exit.

Caveat: this run includes #1522's harness fix (pools/Statements closed before runtime shutdown), so it shows the suite is green and exits cleanly on 23ai — it does not isolate whether the raw destructor path is fixed in 23ai, since the hang precondition (sessions open at exit) no longer occurs.

Deadlock literature search: no public reports of this exact hang found. bccFreeProcess has zero web hits; finiSqora appears only in iRODS#5234 (2020, 11g client, a crash stack during memory exhaustion — not a hang) and an old ODBC doc page. Consistent with the signature being easy to misattribute to a test hang.

21c is an older innovation release; 23ai matches the database server
used in CI and may have fixed or changed the finiSqora client cleanup
path. No public reports of the bccFreeProcess exit deadlock were found
(finiSqora appears only in an unrelated 2020 iRODS crash stack).

Verified locally: all 90 integration tests pass in ~16s with the
23.26.0.0.0 client against Oracle 23.26.2, with a clean process exit.
