Summary

Refactor the deployments frontend feature around clearer module boundaries and feature-local state ownership.

• Align deployment detail tab folders and action surfaces with the product/module boundaries.
• Move shared deployment UI/domain helpers into web/features/deployments/shared and remove re-export-oriented module shapes.
• Clean up list, action, create-guide, release, detail, and route-derived state management with explicit state files, scoped primitives, generated query options, and module README dependency notes.

Fixes: N/A
