feat: add support for SSH RemoteCommand and RequestTTY in host configuration and TUI forms

- Allow users to specify a RemoteCommand to execute on SSH connection, both via TUI and config file
- Add RequestTTY option (yes, no, force, auto) to host configuration and forms
- Update config parsing and writing to handle new fields
- Improve TUI forms to support editing and adding these options
- Fix edit form standalone mode to allow proper quit/save via keyboard shortcuts
