Fix agent assignment permission error in campaign generator workflow

[Copilot]

The campaign generator workflow failed to assign Copilot agents to issues due to insufficient token permissions. The assign-to-agent safe-output was falling back to GITHUB_TOKEN, which cannot execute the replaceActorsForAssignable GraphQL mutation.

Changes

• Configure assign-to-agent to use GH_AW_PROJECT_GITHUB_TOKEN instead of default token

safe-outputs:
  assign-to-agent:
    github-token: "${{ secrets.GH_AW_PROJECT_GITHUB_TOKEN }}"

This follows the same token pattern used by create-project and update-project safe-outputs in the workflow. The token precedence chain for assign-to-agent is: custom token > top-level token > GH_AW_AGENT_TOKEN || GH_AW_GITHUB_TOKEN || GITHUB_TOKEN.
