[Deprecation] Refactor deprecated .hbs component templates to .gjs format

[tejaswiverma121-byte]

Current Behavior

When browsing the discussion forum (e.g., discuss.meshery.io / discuss.layer5.io), the browser developer console displays multiple deprecation warnings for the Layer5 Modern Category + Group Boxes theme component:

Expected Behavior

The theme component templates should follow modern Discourse & Ember standards using .gjs (Glimmer JS template tag format) so that no deprecation warnings are logged and future compatibility with newer Discourse releases is preserved.
