fix(installer): implement robust step-based navigation and fix multi-line sed error

Browse Source 
- Implement a step-based state machine in main loop to support 'Back' navigation via Esc.
- Refactor all prompts to use safe exit-code capture (rc -eq 130/1) and handle 'not submitted' output.
- Add input flushing after Esc events to prevent cascading backtrack signals.
- Add short-circuit checks to every wizard stage for reliable skip-forward behavior.
- Fix sed error when generating multi-disk configurations by escaping newlines in additional_disks.
- Add explicit 'Set a hostname' message to the hostname prompt.
- Convert unsafe short-circuit lists to safe if statements to prevent set -e crashes.
