Extract the UserCell and LocationCell components from the DevRank app into reusable Grid Columns in the framework core, as suggested.

1. Create Components:

   • src/grid/column/GitHubUser.mjs (Column definition)
   • src/component/GitHubUser.mjs (Cell component logic, moved from UserCell.mjs)
   • src/grid/column/CountryFlag.mjs (Column definition)
   • src/component/CountryFlag.mjs (Cell component logic, moved from LocationCell.mjs)

2. Move Styles:

   • Extract SCSS from resources/scss/src/apps/devrank/GridContainer.scss.
   • Create resources/scss/src/grid/column/GitHubUser.scss.
   • Create resources/scss/src/grid/column/CountryFlag.scss.

3. Update DevRank:

   • Refactor apps/devrank/view/GridContainer.mjs to use the new framework columns.
   • Delete local UserCell.mjs and LocationCell.mjs.
