DOC-622 clean up Hybrid docs and add architecture diagram (#26549)

## Summary & Motivation

*Updates hybrid deployment index page to focus on setup and architecture
page to focus on architecture
* Reorganizes agents in sidebar to match ordering on index page
* Adds architecture diagram

 ## Hybrid architecture overview
 
 A **hybrid deployment** utilizes a combination of your infrastructure and Dagster-hosted backend services.
 
-The Dagster backend services - including the web frontend, GraphQL API, metadata database, and daemons (responsible for executing schedules and sensors) - are hosted in Dagster+. You are responsible for running an [agent](/todo) in your environment.

 ## The agent
 
 Because the agent communicates with the Dagster+ control plane over the agent API, it's possible to support agents that operate in arbitrary compute environments.
 
 This means that over time, Dagster+'s support for different user deployment environments will expand and custom agents can take advantage of bespoke compute environments such as HPC.

 ## Security
 
-This section describes how Dagster+ interacts with user code. To summarize:
+Dagster+ Hybrid relies on a shared security model.
+
+The Dagster+ control plane is SOC 2 Type II certified and follows best practices such as:
+- encrypting data at rest (AES 256) and in transit (TLS 1.2+)
+- highly available, with disaster recovery and backup strategies
+- only manages metadata such as pipeline names, execution status, and run duration
+
+The execution environment is managed by the customer:
+- Dagster+ doesn't have access to user code—your code never leaves your environment. Metadata about the code is fetched over constrained APIs.
+- All connections to databases, file systems, and other resources are made from your environment.
+- The execution environment only requires egress access to Dagster+. No ingress is required from Dagster+ to user environments.

 Your agent will send Dagster+ metadata letting us know the run has been launched. Your run's container will also send Dagster+ metadata informing us of how the run is progressing. The Dagster+ backend services will monitor this stream of metadata to make additional orchestration decisions, monitor for failure, or send alerts.

-- encrypting data at rest (AES 256) and in transit (TLS 1.2+)
-- highly available, with disaster recovery and backup strategies
-- only manages metadata such as pipeline names, execution status, and run duration
