Remove SvgDomRenderer Dead Code

[SorraTheOrc]

Summary

Delete obsolete SvgDomRenderer wiring and dead branches once Phaser-native parity is verified.

Player and user experience impact

• Player experience: Card visuals remain visible and correctly occluded by overlays using Phaser layer/depth semantics.
• Developer experience: One consistent rendering path with reduced DOM-specific maintenance overhead.

Acceptance Criteria

• SvgDomRenderer is no longer wired into Main Street production lifecycle.
• Unused imports/types/branches for DOM rendering are removed.
• Build and test gates pass without references to removed DOM path.

Minimal Implementation (end-to-end slice)

• Remove lifecycle wiring/scene fields for SvgDomRenderer.
• Delete or retire SvgDomRenderer module if not used elsewhere.
• Run npm test and npm run build after cleanup.

Dependencies

• Remove DOM Renderer Path
• Unify Shared SVG Texture Pipeline
• Rewrite Overlay Layering Tests
• Harden Texture Cache Invalidation

Deliverables

• Cleanup commit(s)
• Worklog summary comment
