Introduce an HTMX-driven filtering UI and a server-side component for EME initials. The controller Emeinitials.php was simplified (removed inline POST handling in index) and now exposes component_eme_results() which accepts band/mode (defaulting to 'All'), determines the user's date format, loads initials via Emeinitials_model, and returns a partial view. A new view emeinitales/component_results.php renders the results table or a no-data alert. The index view was refactored to an HTMX-enabled filters form, async results container (#emeResults), a Reset button, and a small client-side handler to reset and re-submit the form. These changes enable dynamic filtering without a full page reload and clean up server-side responsibilities.
