Version

Node.js Version

20.18.2

Operating System

Linux (ARM64)

Issue Description

@matter/nodejs-ble is imported statically but declared as optionalDependency, causing crashes when not installed.

File: ws-controller/dist/esm/controller/MatterController.js

import "@matter/nodejs-ble";  //  Crashes if module missing

### Steps to Reproduce

1. Install matter-server in an environment where optional dependencies are excluded
2. Run: `node /usr/lib/node_modules/matter-server/dist/esm/MatterServer.js`
3. Error occurs


### Server Logs

```shell
node /usr/lib/node_modules/matter-server/dist/esm/MatterServer.js
node:internal/modules/esm/resolve:854
  throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
        ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@matter/nodejs-ble' imported from /usr/lib/node_modules/matter-server/node_modules/@matter-server/ws-controller/dist/esm/controller/MatterController.js

Thamks, @julienkolani good catch. In future we will only import it when BLE is enabled - but then it stays an error if the package is not installed
