Follow-up to #1632, which added the template this depends on. Now
rebased onto `main`, so this is just the test change.
## Problem
The firewall transform tests asserted header injection by curling
`httpbin.e2b.team`, an externally hosted service the suite had to keep
alive.
## Fix
Starts a sidecar sandbox from the `httpbin` template instead: the rule
is keyed on the sidecar's `getHost(8080)` and the assertion reads the
injected header back from `/headers`, in the JS, sync Python, and async
Python suites. The sidecar's ready command has already passed by the
time `create` resolves, so the server is serving and no readiness
polling is needed. The template name lives in one fixture per SDK —
`httpbinTemplate` in `tests/template.ts` and the `httpbin_template`
fixture in `conftest.py`.
Also drops two comments merged in #1632 that claimed the tests spawn
`e2b/httpbin`. The bare alias is what resolves, same as `base` — the
team slug only appears in the display name.
⚠️ Do not merge before **Build and push prepared templates** has been
dispatched with `template: httpbin` — the tests resolve the template by
name and fail until it exists on the E2B team.
Verified against production: all three tests pass with the injected
header reflected by the sidecar, spawning the template by its bare alias
with a key that owns it — the same situation as CI.
