Rename all 1,169 components to path-based names with namespace support

Component names now reflect filesystem location using / as path separator
and : as namespace separator for shared components:
  ~sx-header → ~layouts/header
  ~layout-app-body → ~shared:layout/app-body
  ~blog-admin-dashboard → ~admin/dashboard

209 files, 4,941 replacements across all services.
