Show the safe OpenClaw PopiArt skill install path

The public site now points OpenClaw users at the dedicated popiartcli skill directory and raw SKILL.md copy path, so installers do not scan runtime PopiSkills as agent skills.

Constraint: The server worktree already contains unrelated billing and UI edits, so this commit is intentionally limited to the homepage content and renderer.

Rejected: Document only in popiartcli README | users may follow the website install flow instead.

Confidence: high

Scope-risk: narrow

Directive: Keep OpenClaw installation guidance pointed at popiartcli/tree/main/skill, not a repository-root skills directory.

Tested: npm run build in web

Not-tested: Live deployed website smoke test.
