Update placeholder values, documentation URLs, icon names, and registry identifiers across 14 template files to reflect the molodetz rebranding. Changes include LDAP group filter placeholders, help link URLs, SVG icon prefixes, organization names in devtest, install page domain examples, and package registry documentation links for Alpine, Cargo, Chef, Composer, Conan, and Conda.
- Wrapped file view, blame, and directory listing sections inside `{{if .IsSigned}}` blocks to restrict content visibility to authenticated users.
- Moved `repo/sub_menu` template inclusion into the signed-in block for both home and directory views.
- Added duplicate `{{if .IsSigned}}` check and redundant template calls for view_file, blame, and view_list to correct nested conditional structure.
- Removed `{{if .IsSigned}}` guard from the original `repo/sub_menu` call to prevent double rendering and align with new layout.
