Overview

Resolves issue #1349 by connecting the Guild Profile page to backend guild data endpoints, deriving the authenticated user's isCaptain status, and introducing a clear preview indicator with interactive join states.

Key Changes

1. Dynamic Guild Data Ingestion:
   • Adds an asynchronous loadGuild effect querying ${apiBase}/v1/guilds/${id} to populate guild name, captain handle, win rate, rank, and member roster.
   • Provides safe fallback defaults when endpoints are staging sandbox data.
2. Authenticated Captain Role Resolution:
   • Leverages useAuth() to compare user.username against guild.captainName, dynamically enabling isCaptain permissions and conditional captain management panels.
3. Interactive Preview Experience:
   • Displays a clean Preview Mode banner informing visitors of ongoing guild contract deployment.
   • Replaced dead placeholders with functional join submission alerts and accessible table rendering.

Local Quality Assurance & Verification

• Tested captain detection with matched and unmatched session profiles.
• Verified responsive table view and status notification dismissal.

Closes #1349
