feat: add TemplateBuilderCreateTemplate SDK types and client method (#26360)

Adds `POST /api/v2/templatebuilder/compose/template`, a synchronous
endpoint that composes a template from a base and modules, validates it
via a provisioner import job, and creates the template in a single
request.

The handler composes terraform files, bundles them as a tar, inserts the
file with hash-based dedup, creates a template version with an import
job, waits up to 2 minutes for the job to complete, classifies errors
for known failure modes (network-unreachable registry, DNS failures),
then creates the template on success. Canceled and failed jobs return
appropriate error responses.

Also adds `hclwrite.Format` to composed terraform output for canonical
HCL formatting.

Closes https://linear.app/codercom/issue/DEVEX-279

<details>
<summary>Implementation notes</summary>

- SDK types and client method in `codersdk/templatebuilder.go` with
validation tags matching the standard template creation path
(`template_display_name`, `lt=128`)
- `ClassifyProvisionerError` in `coderd/templatebuilder/errors.go`
detects DNS, connection refused, i/o timeout, and TLS handshake failures
and returns actionable messages
- `waitForProvisionerJob` polls with a ramp-up interval schedule (100ms,
200ms, 500ms, then 1s steady) and accepts an `onUpdate` callback for
future SSE streaming
- Audit logging for both template and template version creation
- TOCTOU name uniqueness: early check for fast feedback, DB unique
constraint catch for the race window (returns 409, not 500)
- Swagger annotations for all error responses (400, 404, 409, 504)
