docs(oracle): move clienti/ under lxc108-oracle/

clienti/ contained Oracle XE 21c troubleshooting and PDB recreation
scripts. Moving it under proxmox/lxc108-oracle/ keeps Oracle migration
material colocated with the Oracle host docs. Update the two relative
links in roa-windows-setup that pointed to the old location.
