Pull request overview

Refactor connections/friends UX to Solid + TanStack collections/queries, removing legacy friends/blocked-users DOM logic and snapshot-stored connections.

Changes:

• Add collections/connections (tanstack/solid-db) + queries/friends (solid-query) as new data sources.
• Replace legacy friends page + blocked users table with Solid DataTable pages/components mounted via <mount>.
• Move shared “age” formatting into utils/date-and-time.ts and update friend indicators to use the new collection.
