[codex] Add deployment details review before starting models

[xu16601526267]

Summary

• Replace direct model-list deployment with a deployment details modal for reviewing AIMA recommendations before startup.
• Add editable engine, resource policy, slot, port, and launch parameter controls, plus model info, quantization, VRAM estimate, and tuning suggestions.
• Wire edited parameters into both deploy.dry_run and deploy.run, persist device-local defaults through backend deploy.defaults, and close the modal immediately after confirming startup.

Validation
