fix(deps): replace cx_Oracle with oracledb (Python 3.12 compatible)

cx_Oracle 8.3.0 has no Python 3.12 wheels and its setup.py fails in
pip's isolated build environment. oracledb is Oracle's official
replacement (released 2022, has binary wheels for all platforms).

Add a backward-compatibility shim so existing cx_Oracle code continues
to work without changes to callers.
