Matches the proto field server_scaled_provider_cloud_run
(temporalio/api#799).

* feat(deployments): simplify create worker deployment UX

Redesigns the create serverless worker deployment form with a two-card
layout (Configuration + Compute), compute provider selection (Lambda /
GCP Cloud Run), provider-conditional fields, and a collapsible IAM role
setup guide with CloudFormation and Terraform tabs.

- Auto-generates Build ID with a random hex value
- Adds GCP Cloud Run provider fields and buildGcpCloudRunComputeConfig
- Stores CFN and Terraform templates as raw files (?raw imports)
- Accepts cfnTemplate and cfnTemplateUrl props so cloud-ui can supply
  hosted S3 templates and Launch Stack deep links
- Removes unused serverless-worker-setup-guide and setup-guide-toggle

* feat(deployments): support Cloud Run across version forms and omit scaler until supported

- Extract shared provider Resource/Access/Scaling sections into
  compute-fields.svelte; create deployment, create version, and edit
  version forms all render identical provider-specific sections
- Add provider + GCP fields to create/edit version schemas with
  conditional validation (shared superRefine)
- Build GCP Cloud Run compute config in version create/edit pages;
  infer initial provider from stored config when editing
- Omit the scaler block for Cloud Run requests: no worker-set
  compatible scaling algorithm exists server-side yet; scaling
  section shows a Coming Soon badge with Customize disabled
- Decode and render GCP provider details (worker pool, project,
  region, service account) in the expanded version row

* feat(deployments): gate Cloud Run provider behind cloudRunEnabled prop

Cloud Run radio card renders disabled with a Coming Soon badge unless
cloudRunEnabled is passed. OSS routes enable it; cloud-ui can wire the
prop to a feature flag and flip it when the backend is ready.

* feat(deployments): gate Cloud Run behind gcpCloudRunDeployments capability

The provider picker reads the gcpCloudRunDeployments system capability
directly (via a new hasCapability helper, also adopted by
CapabilityGuard) and renders the Cloud Run radio card disabled with a
Coming Soon badge when absent. The field doesn't exist in the published
api proto yet, so OSS shows Coming Soon until the server advertises it;
cloud-ui enables it by mapping a feature flag into its synthesized
systemInfo capabilities, same as serverScaledDeployments.

* rename capability to serverScaledProviderCloudRun

Matches the proto field server_scaled_provider_cloud_run
(temporalio/api#799).

* address review: randomUUID build id, decode by provider type

- buildId default uses crypto.randomUUID()
- provider detail decoders short-circuit unless the scaling group's
  provider type matches, instead of both running on every config
