Fix ROA Windows setup scripts for Oracle XE deployment

Key fixes:
- Add Run.cmd/RunAll.cmd wrappers with ExecutionPolicy Bypass
- Add Get-ListenerHost() to auto-detect listener IP address
- Fix impdp connection using EZConnect format (host:port/service)
- Add parallel=1 for Oracle XE compatibility
- Fix Write-Log to accept empty strings with [AllowEmptyString()]
- Fix Get-SchemaObjectCount regex for Windows line endings (\r\n)
- Fix path comparison for DMP file copy operation
- Add GRANT EXECUTE ON SYS.AUTH_PACK TO PUBLIC for PACK_DREPTURI
- Fix VAUTH_SERII view to use SYN_NOM_PROGRAME (has DENUMIRE column)
- Add sections 10-11 to grants-public.sql for SYS object grants

Tested on VM 302 (10.0.20.130) with Oracle XE 21c.
