feat(FR-1371): Add model deployment launcher UI

[agatha197]

Resolves #4144 (FR-1371)

Add Deployment Launcher Page

This PR adds a new deployment launcher page that allows users to create model deployments through a step-by-step wizard interface. The launcher guides users through configuring deployment metadata, network settings, deployment strategies, initial revision details, and resource allocation.

Key features:

• Three-step wizard interface (Deployment, Initial Revision, Confirm & Deploy)
• Form state persistence in URL parameters for easy sharing and navigation
• Comprehensive preview screen before final deployment
• Support for various deployment strategies (Rolling, Blue-Green)
• Configuration options for runtime variants, model mounts, and environment variables

The PR also adds navigation from the deployment list page to this new launcher and integrates with the existing deployment system.

Checklist:

• Documentation
• Minium required manager version
• Specific setting for review (eg., KB link, endpoint or how to setup)
• Minimum requirements to check during review
• Test case(s) to demonstrate the difference of before/after
