[1.17] - disable-init-endpoints annotation

[tomflenner]

What content needs to be created or modified?

Documentation needs to be created explaining the new configuration options to disable initialization endpoints (/dapr/config and /dapr/subscribe) introduced in PR #9077. This feature allows users to optionally disable HTTP requests to these endpoints during Dapr initialization on a per-application basis.

Describe the solution you'd like

The documentation should cover:

• Overview of the new --disable-init-endpoints CLI flag for dapr run
• Description of the corresponding Kubernetes sidecar annotations (dapr.io/disable-init-endpoints)
• Explanation of supported values: config and subscribe
• Use cases for disabling these endpoints:
  • Reducing log noise when applications don't use programmatic subscriptions or config loading
  • Avoiding confusion for developers who see failed endpoint calls in logs

Where should the new material be placed?

The documentation should be placed in the following locations:

• Primary location: https://docs.dapr.io/reference/arguments-annotations-overview/
• Secondary location: https://docs.dapr.io/developing-applications/building-blocks/configuration/configuration-api-overview/
• Additional reference: https://docs.dapr.io/developing-applications/building-blocks/pubsub/subscription-methods/#programmatic-subscriptions

The associated pull request from dapr/dapr, dapr/components-contrib, or other Dapr code repos
