fix(ui-ux): add category page filters, sorting, and stats

[9876543210-tc-0123456789]

Summary

Closes #1958.

Upgrade /wiki/category/*/ pages from flat title lists into filterable, sortable topic directories that also expose the per-article stats already computed by articles.json.

Why This Should Ship

Large category hubs like Subnets are hard to scan when every card only shows a title and summary. Reusing the existing backlinks/reference/revision/word/section/read-time data gives readers a fast way to spot the newest, largest, and most connected entries without opening every article.

Review Notes

• Replaces closed fix(ui-ux): add category page directory controls #1957 and fix(ui-ux): add category page filters, sorting, and stats #1959 with a smaller focused submission plus motion evidence.
• Scope is limited to /wiki/category/*/ HTML pages; no dependency, workflow, or policy changes.
• Reuses the stats already computed for the paired articles.json route instead of introducing a new data artifact.
• CI starts on this PR; the current repo-local npm run build is also in progress because this repository regenerates article history before Astro emits pages.

Visual Evidence

• Page URL: /wiki/category/Subnets/
• Viewport width: 1440px
• Action taken in clip: load the page, use Filter articles with subnet 9, then switch Sort articles to Most backlinks and Recently updated.
• Expected before behavior: the category hub is a flat title-and-summary list with no filter control, no sort control, and no visible per-article stats.
• Expected after behavior: the page exposes in-place filter/sort controls, updates the visible result set without a reload, and shows backlinks, references, revisions, words, sections, reading time, and last-updated metadata on each card.
• Motion evidence: https://tmpfiles.org/dl/wdwpb0oGBcra/category-after.webm

Target Branch

• This PR targets test
• This PR targets main only because it promotes test to production

Security Checklist

• No secrets, tokens, build hooks, wallet seeds, or private endpoints are included
• No unnecessary workflow, dependency, or deployment changes
