refactor(deploy): make deploy CLI model-first (typed DeploymentConfig)

[desertaxle]

Summary

• Loader now returns DeploymentConfig models instead of dicts
• CLI applies flags directly onto models for strong typing
• Core deploy path resolves/normalizes on the model, then dumps to dicts only when building RunnerDeployment
• Keeps behavior for defaults, templating, actions; fixes legacy schedule: {} promotion

Details

• _load_deploy_configs_and_actions: returns list[DeploymentConfig] + actions dict
• Selection helpers (_parse_name_from_pattern, _filter_matching_deploy_config, _handle_pick_deploy_*) accept models and convert to dicts for prompt/display and downstream execution
• _apply_cli_options_to_deploy_config: takes/returns DeploymentConfig; merges params, variables and work-pool fields; accepts dict concurrency_limit and validates into ConcurrencyLimitSpec
• _handle_deprecated_schedule_fields: typed to DeploymentConfig; only promotes schedule to schedules if non-empty when dict (avoids schedule: {} errors)
• _run_single_deploy: dict -> model -> resolve blocks/vars/env -> apply options -> template -> dump JSON for RunnerDeployment construction

Why

• Strengthens typing across deploy CLI, reducing key typos and easing refactors
• Minimizes blast radius by retaining dicts at integration boundaries

Testing

• Reproduced and fixed TestProjectDeploy::test_project_deploy locally
• Can run full CLI deploy suite if desired

Follow-ups

• Consider migrating remaining deploy helpers to model-first or adding mypy coverage for deploy package.
