Refactor unlockers command structure and add quiet flag to list command

- Rename 'unlockers' command to 'unlocker' for consistency
- Move all unlocker subcommands (list, add, remove) under single 'unlocker' command
- Add --quiet/-q flag to 'secret list' for scripting support
- Update documentation and tests to reflect command changes

The quiet flag outputs only secret names without headers or formatting,
making it ideal for shell script usage like: secret get $(secret list -q | head -1)
