remove simplest topology, leave only two

[Tofel]

This PR removes simplest topology to reduce complexity, number of tests run in the CI and to align them with what we have in staging & production.

Bootstrap node has been removed from the workflow DON and moved to a separate DON. That bootstrap node will also always play the role of the gateway to limit the memory footprint.

Removing bootstrap from the workflow DON was mainly done to fix gateway job configuration, which previously included the bootstrap node in the set of nodes that were whitelisted for the gateway. That caused an error, when gateway had to process an incoming request, e.g. via web API trigger, because bootstrap node wasn't maintaining a connection with the gateway node. We adjusted the topology to match the job changeset logic.

Bonuses:

• fixed consensus v2 job filter: previously the bootstrap job would always be created on the same DON where the capability lived instead of the DON to which bootstrap node belongs
• fixed EVM v2 capability job configuration: previously all configs used the node address of the first node in the DON instead of the actual node

Pull request overview

This PR simplifies the test topology by removing the "simplest" (workflow-don) configuration and retaining only two topologies: workflow-gateway-don and workflow-gateway-capabilities-don. The bootstrap node has been moved from the workflow DON to a separate bootstrap DON that also serves as the gateway node, aligning with production/staging configurations.

Key changes:

• Bootstrap node moved to a separate DON that combines bootstrap and gateway roles
• Workflow DON reduced from 5 to 4 nodes (no longer includes bootstrap)
• Fixed consensus v2 bootstrap job to use correct DON name
• Fixed EVM v2 capability configuration to use correct node address per worker
