[Phase 2.3] Build feedback detail view

[Andreas-Froyland]

Goal

Full detail page for a single feedback item. The destination when clicking a card from the listing.

Depends on: #11 (listing) - users navigate here from the list

Content

• Title — large, prominent
• Description — rendered as markdown
• Category badge — colored, matches listing
• Status badge — Open / In Progress / Done / Closed
• Author — GitHub avatar + username, or "Anonymous" with generic icon
• Timestamp — "Created 3 days ago"
• Vote button placeholder — implement in [Phase 2.4] Implement upvoting system #12
• Linked GitHub issue — if linked, show issue number + title as a clickable link to GitHub (Phase 4)
• Back link — easy return to listing (preserves filters)

Org admin extras (if signed in as admin)

• Status dropdown to change feedback status ([Phase 5.3] Feedback status management for org admins #21)
• "Push to GitHub" button (Phase 4, but reserve the UI slot)
• Delete option

URL structure

/[org]/[project]/feedback/[id]
— works both on the internal dashboard and the public portal

Notes

• This view is the foundation for upvoting ([Phase 2.4] Implement upvoting system #12) and GitHub integration (Phase 4)
• Keep it clean and focused - all the key info at a glance
