feat: Add alpine variant support for LXC scripts

- Download alpine install scripts (alpine-{slug}-install.sh) when alpine variant exists
- Add ScriptVersionModal component for version selection (default/alpine)
- Update ScriptDetailModal to show version selection before server selection
- Update script execution to use selected version type
- Support downloading both default and alpine variants of scripts
