Refactor: Dynamic Year Fields in Contributor Model

Refactor apps/devrank/model/Contributor.mjs to dynamically generate year fields (current year down to 2010) instead of using a hardcoded list.

This approach:

1. Ensures the model automatically includes the current year (e.g., 2026) without manual updates.
2. Reduces boilerplate code.
3. Mirrors the dynamic column generation logic in GridContainer.mjs.

Implementation Details:

• Remove the hardcoded year fields from static config.fields.
• Implement a dynamic generation logic (likely in onConstructed or a dedicated method called during class setup/init, though Neo.data.Model fields are usually static. For Models, we might need to stick to static definition or use a static block / IIFE to generate the array before assignment if we want it to be truly dynamic at load time).
• Actually, Neo.data.Model processes fields in processFields. We can assign the fields array dynamically in the class definition itself using standard JS execution.

Example:

const fields = [...staticFields];
const currentYear = new Date().getFullYear();
for (let i = currentYear; i >= 2010; i--) {
    fields.push({name: `y${i}`, mapping: `years.${i}`, type: 'Integer'});
}
// assign fields to config
