refactor: replace axios with native HTTP calls

[adiologydev]

Changes

Remove axios dependency from both root and coolify-realtime packages. Terminal server now uses an httpPost helper built on Node's http module (Soketi image is locked to Node 16 which lacks global fetch). Updated public/js/echo.js from laravel-echo v1.15.3 to v2.2.7 (matches package.json).

Note: We should migrate to Laravel Reverb, socketi last updated 4 years ago.

Walkthrough

This pull request removes the axios HTTP client library from both the root and realtime service dependencies, and replaces its usage in the terminal server with a custom httpPost utility function that uses Node's built-in http.request. A new httpPost helper is exported from terminal-utils.js to handle POST requests with simplified response handling. Additionally, the Laravel Echo JavaScript library is updated to a newer version with changes to channel helper methods and event handling logic. The terminal authentication and IP retrieval flows now use the new utility instead of the external dependency.
