refactor: explicit initialization and dependency injection

- Replace init() with config.Load() function when loading env variables - Inject portRegistry into session, server, and lifecycle structs - Inject sessionRegistry directly into interaction and lifecycle - Remove SetSessionRegistry function and global port variables - Pass ssh.Conn directly to forwarder constructor instead of lifecycle interface - Pass user and closeFunc callback to interaction constructor instead of lifecycle interface - Eliminate circular dependencies between lifecycle, forwarder, and interaction - Remove setter methods (SetLifecycle) from forwarder and interaction interfaces
refactor(interaction): separate view and update logic into modular files

+| `NODE_TOKEN` | Authentication token sent to controller in `node` mode | - (required in `node`) | Yes (node mode) |

 **Note:** All environment variables now use UPPERCASE naming. The application includes sensible defaults for all variables, so you can run it without a `.env` file for basic functionality.
