feat: add sort and status filter to dashboard article list

[Copilot]

Dashboard article list had no sorting or filtering — all articles were returned newest-first with no way to filter by publish status.

Changes

Backend

• myArticleInput schema — adds sort_by (created_at | title | published_at, default created_at), sort_order (asc | desc, default desc), and status (all | published | draft, default all)
• myArticles action — applies dynamic orderBy via sqlkit asc/desc and status filter via isNull/isNotNull on published_at; adds asc, isNull, isNotNull to sqlkit imports

Frontend (DashboardArticleList)

• Adds useState for sortBy, sortOrder, status; all three are included in the TanStack Query queryKey so the list refetches on change
• Renders a toolbar below the header:
  • Status tabs: All / Published / Draft (segmented button group)
  • Sort field dropdown: Created at / Title / Published at
  • Order toggle: ↑ Ascending / ↓ Descending
• cancelQueries in both optimistic-update mutations updated to use the full query key

// query key now tracks sort state — changing any control triggers a fresh fetch
queryKey: ["dashboard-articles",sortBy,sortOrder,status]

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/graphql
  • Triggering command: /usr/bin/gh gh issue list (http block)
  • Triggering command: /usr/bin/gh gh issue list --state open (http block)
  • Triggering command: `/usr/bin/gh gh issue comment 108 --body ## Summary

Implemented a sorter/filter toolbar in the dashboard article list as requested in #108.

What Changed

Backend (src/backend/services/inputs/article.input.ts)

• Extended myArticleInput Zod schema with three new optional fields (all w` (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
