Fix ROA Windows setup scripts discovered during VM 302 testing

- 03-import-contafin.ps1: Auto-detect DMP file when not specified
- 05-import-companies.ps1: Default DumpDirectory to C:\DMPDIR
- 08-post-install-config.ps1: Fix SERVER_INFO column names (NAME/VALUE)

Tested full installation on VM 302 (Oracle XE 21c):
- CONTAFIN_ORACLE: 344 objects imported
- CAPIDAVATOUR: 3418 objects imported
- 54 ROAUPDATE directories created
- Scheduler jobs configured
