Subject: [PATCH] scripts: fix create-host flake.nix insertion point

Fix bug where new hosts were added outside of nixosConfigurations block
instead of inside it.

Issues fixed:
1. Pattern was looking for "packages =" but actual text is "packages = forAllSystems"
2. Replacement was putting new entry AFTER closing brace instead of BEFORE
3. testvm01 was at top-level flake output instead of in nixosConfigurations

Changes:
- Update pattern to match "packages = forAllSystems"
- Put new entry BEFORE the closing brace of nixosConfigurations
- Move testvm01 to correct location inside nixosConfigurations block

Result: nix flake show now correctly shows testvm01 as NixOS configuration
