feat: Add confirmation modal for script installation and server sorting (#105)

- Add confirmation modal when only one server is saved
- Show script name and server details in confirmation view
- Auto-select single server but require user confirmation
- Preserve existing behavior for multiple servers (no pre-selection)
- Sort servers alphabetically by name in all components
- Fix ESLint issues with nullish coalescing operators

Fixes: PROX2 now appears before PROX3 in server lists
