The current implementation of the User and Location columns in apps/devrank/view/GridContainer.mjs uses an anti-pattern where the component config function returns a raw vdom object. This leads to component.set({vdom: ...}) calls, which are problematic (stale state, ID loss).

The goal is to refactor these into dedicated component classes (UserCell, LocationCell) that manage their own VDOM updates reactively based on input configs. This will fix the stale rendering issues and align with proper Neo.mjs architectural patterns.

Tasks:

1. Revert debug logs in src/grid/column/Component.mjs.
2. Create apps/devrank/view/cell/UserCell.mjs.
3. Create apps/devrank/view/cell/LocationCell.mjs.
4. Update apps/devrank/view/GridContainer.mjs to use these new components.
