Add ROA Oracle Database Windows setup scripts with old client support

PowerShell scripts for setting up Oracle 21c/XE with ROA application:
- Automated tablespace, user creation and imports
- sqlnet.ora config for Instant Client 11g/ODBC compatibility
- Oracle 21c read-only Home path handling (homes/OraDB21Home1)
- Listener restart + 10G password verifier for legacy auth
- Tested on VM 302 with CONTAFIN_ORACLE schema import
