lsregistration: clarify save/extract + SELinux relabel + checksum updates

[ShawnMcKee]

Clarify save vs extract for lsregistration updater; add SELinux relabeling and update checksums.

Summary

• Help text: clarify that 'save' writes a raw .conf file and 'extract' produces an executable restore script.
• SELinux: the updater now attempts to apply 'restorecon' after writing configuration (host or inside container) when available; 'extract' also generates a script that attempts 'restorecon' when run on a host.
• Version bump: → 1.0.1 and corresponding checksum updates.
• Docs: updated , Quick Deploy examples, and CHANGELOG to document behavior and usage.
• Installer: removed deprecated from the fetched helpers list and updated .

Testing

• Syntax:
• Save conf:
• Extract script:
• Dry-run restore:

Notes

• SELinux relabeling () is a best-effort step and will be skipped with a log entry if isn't present.
• Happy to add an optional integration test that runs and then executes the produced restore script on a test host if desired.
