fix: eliminate 4.3 MB Phosphor icon client chunk

[mvvmm]

Summary

Replaces the full @iconify-json/ph/icons.json import in PhosphorIcon.tsx (27,693-line JSON containing every Phosphor icon) with six ?raw SVG imports from @phosphor-icons/core for the only icons actually used by React islands: thumbs-up, thumbs-down, check-circle, magnifying-glass, x, check-bold.

The full-set import produced a 4.3 MB client-side JS chunk (PhosphorIcon.cbrmX4Sq.js) that shipped to every page with a feedback widget or resource selector. The replacement inlines ~2 KB of SVG markup total, eliminating the chunk entirely.

Metric	Before	After
PhosphorIcon chunk	4.3 MB	gone (inlined into consumer chunks)
Chunks > 500 KB	2	1

The name prop is now a union type (keyof typeof icons) instead of string, providing compile-time safety for unknown icon names rather than a runtime throw.

👉 Fix in your agent 👈

Fix the following review findings in PR #32575 (https://github.com/cloudflare/cloudflare-docs/pull/32575).

Before making changes, review each finding and present a brief summary table:
- For each finding, state whether you agree, disagree, or need clarification
- If you disagree (e.g. the fix requires disproportionate effort for minimal benefit,
  or the finding is factually incorrect), explain why
- If you need clarification before deciding, ask those questions
- Then share your plan for which issues to tackle and in what order

After triaging, follow this order:
1. Post a comment on this PR for any findings you are skipping, with the finding ID and your reasoning.
2. Then commit the fixes for the legitimate findings.

The comment must come before the commit — the bot reads PR comments when a new
push triggers a review, so skip comments posted after the push will be missed.
