feat(scripts): add Windows .bat launcher for relink_manual_invoices

Sets the Oracle thick-mode env (TNS_ADMIN + instant client PATH) like start.bat,
resolves venv/script paths relative to itself, forwards all args, and pauses so
output is readable. Run on the VENDING prod server (double-click = dry-run).
