feat(ping): implement ping communication and visual enhancements

This commit implements the full communication loop for the ping system, including:

-   **Schema Definitions:** Added  and  schemas.
-   **Client-Side Sending:** Configured  to emit , which  now intercepts and uses to send  to the server.
-   **Server-Side Execution:** Implemented  to process , generating  (for chat) and  (for visual pings) for friendly players.
-   **Client-Side Receiving:**  handles  by emitting  for local display.
-   **Visual Enhancements:** Updated the ping animation with a glow effect, adjusted duration to 6 seconds, and increased maximum radius to 48 for a more prominent visual.
-   **Test:** Added a unit test for  to verify server-side logic.
