[codex] Add deploy modal image preflight parity

[xu16601526267]

Summary

Adds the 212 deploy modal parity pieces on top of develop without changing backend deploy contracts.

• Adds the image architecture preflight section to the deploy modal.
• Adds deploy compatibility i18n, display helpers, and engine asset/image-aware labels.
• Adds dry-run sequence invalidation so stale preflight responses do not overwrite current modal state.
• Keeps dirty config state from showing stale compatibility results.
• Adds static UI coverage for the new deploy modal tokens and dry-run guard behavior.

Validation

• go test ./internal/ui
• Inline index.html script parsing with Node
• git diff --check
• WSL: go test -buildvcs=false ./...

Note: WSL uses -buildvcs=false because this local checkout is a Windows git worktree and WSL cannot resolve the Windows .git/worktrees path metadata directly.
