fix(agent): project available commands in management rows (#579)

## Summary
- Add `available_commands` to the `AgentManagementRow` API payload.
- Project persisted handshake available command catalogs through
management rows and by-id reads.
- Extend registry coverage and update test row builders for the new
field.

## Test Plan
- `cargo test -p aionui-ai-agent
management_rows_project_runtime_catalogs_from_agent_metadata`
- `cargo test -p aionui-api-types`
- `cargo test -p aionui-assistant
list_maps_generated_definition_to_generated_source`
- `cargo test -p aionui-app
management_endpoint_keeps_deprecated_runtime_rows_for_diagnostics`
- `cargo fmt --all -- --check`
- `git diff --check`
- `just push -u origin fix/management-available-commands`
