refactor(web): use ghost-muted where ghost buttons restyled to muted

[juliusmarminge]

Fourteen ghost buttons re-declared text-muted-foreground and
hover:text-foreground through className. That combination is exactly the
ghost-muted variant (same icon tint, same hover surface), so swap them over
and drop the classes. No rendered change.

Lowers the no-restyle ceiling from 1146 to 1124.

Layer 1 of 24 in stack #13044, ordered least to most opinionated. Part of the components/ui className cleanup (audit and guardrail: #12982). Each layer lowers the shadcn/no-restyle ceiling; CI fails if the count rises. For every override cluster the question was "is this a real design-system concept, or should the primitive get stricter and the consumers change?"; a prop was only added for the former.

Approvability

Verdict: Approved at d1cfcfe

Macroscope's review found this PR approvable — This PR centralizes existing muted ghost-button styling across several web views without changing actions, data flow, or accessibility behavior. The accompanying lint-gate update tightens enforcement, making the overall change low risk.

Right; dropped the hover override. The copy button is a plain ghost-muted now.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve the transparent hover and pressed states.

ghost-muted adds bg-accent on hover and press. This button previously used transparent states. Removing those classes changes the rendered behavior. Keep the transparent-state classes or use a variant that preserves them.
