Subject: [PATCH 01/23] Detect active deployments before provisioning (#7248)

Before starting a Bicep deployment, check the target scope for
in-progress ARM deployments and wait for them to complete. This avoids
the DeploymentActive error that ARM returns after ~5 minutes when a
concurrent deployment is already running on the same resource group.

Changes:
- Add IsActiveDeploymentState() helper in azapi to classify provisioning
  states as active or terminal.
- Add ListActiveDeployments() to the infra.Scope interface and both
  ResourceGroupScope / SubscriptionScope implementations.
- Add waitForActiveDeployments() in the Bicep provider, called after
  preflight validation and before deployment submission. It polls until
  active deployments clear or a 30-minute timeout is reached.
- Add a DeploymentActive error suggestion rule to error_suggestions.yaml.
- Add unit tests for state classification, polling, timeout, error
  handling, and context cancellation.

Fixes #7248

 extract filter helper, refresh timeout names

- Fix 'range 200' compile error (not valid in all Go versions)
- Make DeploymentActive YAML rule scope-agnostic
- Extract filterActiveDeployments helper to deduplicate scope logic
- Refresh deployment names from latest poll on timeout message

Subject: [PATCH 08/23] Fix: remove ListActiveDeployments from Scope interface

Move ListActiveDeployments to a standalone function instead of adding
it to the exported Scope interface. Adding methods to exported
interfaces is a breaking change for any external implementation
(including test mocks in CI).

The standalone infra.ListActiveDeployments(ctx, scope) function calls
scope.ListDeployments and filters for active states, achieving the
same result without widening the interface contract.

Subject: [PATCH 10/23] Fix: use scopeForTemplate instead of deployment for
 active check

The deployment object returned by generateDeploymentObject embeds a
Scope that can be nil in test environments (e.g. mockedScope returns
an empty SubscriptionDeployment). Using scopeForTemplate resolves
the scope from the provider's configuration, avoiding nil panics
in existing tests.

Subject: [PATCH 11/23] Fix review: handle ErrDeploymentsNotFound in poll loop

If the resource group is deleted externally while waiting for active
deployments to drain, the poll now returns nil instead of surfacing
a hard error. This matches the initial check behavior.

Known limitations documented:
- Only queries the active deployment backend (standard or stacks)
- Race window between wait completion and deploy request is inherent

Subject: [PATCH 15/23] Scope active deployment check to current deployment
 name

Filter active deployment detection by the current deployment name so
parallel CI runs using different env-names (and therefore different ARM
deployment names) don't block each other. ARM allows concurrent
deployments with different names at the same scope.

Added ListActiveDeploymentsByName to scope.go that filters by both
name and active provisioning state. Updated waitForActiveDeployments
to accept and pass through the deployment name.

Subject: [PATCH 19/23] Make active deployment check best-effort to avoid
 blocking recorded tests

The ListDeployments call was added by this PR but isn't present in
existing test recordings. When recorded functional tests replay
without this API response, the check fails and blocks the entire
deploy. Since the active deployment check is a pre-flight
optimization (not a correctness requirement), log and proceed
on errors instead of failing.

Remove ListActiveDeployments and filterActiveDeployments which
