## Context
This commit is part of the fix for a downstream provider outage observed
during
`coderd_template` updates.
Observed downstream symptoms (terraform-provider-coderd):
- Template-version websocket log stream requests returned `401`:
`GET /api/v2/templateversions/<id>/logs`.
- In older provider code (`waitForJob`), stream-init errors could
produce
`(nil, nil, err)` and then trigger a nil dereference when
`closer.Close()`
was deferred before checking `err`.
- Net effect: template update path crashed instead of returning a
controlled
provisioning error.
That provider panic is being hardened in the provider repo separately
(https://github.com/coder/terraform-provider-coderd/pull/308). This
commit addresses the upstream SDK auth mismatch that caused the
websocket `401`
side of the chain.
## Root cause
On deployments with host-prefixed cookie handling (dev.coder.com)
enabled
(`--host-prefix-cookie` / `EnableHostPrefix=true`), middleware rewrites
cookie
state to enforce prefixed auth cookies.
For non-browser websocket clients that still sent unprefixed
`coder_session_token` via cookie jars, this created an auth mismatch:
- cookie-based credential expected by the client path,
- but cookie normalization/stripping applied server-side,
- resulting in no usable token at auth extraction time.
## Fix in this commit
Apply the #22226 non-browser auth principle to remaining websocket
callsites in
`codersdk` by replacing cookie-jar session auth with header-token auth.
