fix: What's New v1.3.0, backend bind 127.0.0.1 in deploy + systemd, dead man's switch permissions

- Added v1.3.0 release notes to Settings "What's New" modal
- Deploy script now auto-fixes backend bind address (0.0.0.0 → 127.0.0.1)
- All image-recipe systemd/service files updated to 127.0.0.1
- Fixed dead man's switch: alert-config.json owned by root, now chown'd
- Removed unused toggleAutoSync function (build error)
- Deploy script adds LND REST port 8080 to Tor config generation
