Mish Ushakov 3c5684275c fix(js-sdk): pass sandbox headers to EnvdApiClient (#1175)
## Summary
- Fixes `Sandbox.create()` failing in self-hosted environments because
`sandboxHeaders` were not propagated to `EnvdApiClient`
- Spreads `sandboxHeaders` (`E2b-Sandbox-Id`, `E2b-Sandbox-Port`) into
the headers passed to the envd API client

Closes #1158
Based on #1159 by @ajuijas

## Test plan
- [ ] Verify sandbox creation works in self-hosted environments
- [ ] Verify sandbox headers are correctly passed to EnvdApiClient

What is E2B?

E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.

Run your first Sandbox

1. Install SDK

npm i @e2b/code-interpreter

2. Get your E2B API key

  1. Sign up to E2B here.
  2. Get your API key here.
  3. Set environment variable with your API key
E2B_API_KEY=e2b_***

3. Execute code with code interpreter inside Sandbox

import { Sandbox } from '@e2b/code-interpreter'

const sbx = await Sandbox.create()
await sbx.runCode('x = 1')

const execution = await sbx.runCode('x+=1; x')
console.log(execution.text)  // outputs 2

4. Check docs
