Subject: [PATCH] fix: Properly fetch blossom servers for any profile view

**Problem:**
Blossom servers were only visible for the logged-in user's profile,
not for other users' profiles being viewed.

**Solution:**
Enhanced ProfileViewer blossom server fetching with multi-layer approach:

1. **Cache-first loading**: Check blossomServerCache for instant display
2. **EventStore check**: Use existing cached event if available
3. **Reactive subscription**: Subscribe to EventStore for real-time updates
4. **Network fetch**: Use addressLoader to fetch latest from relays
5. **Auto-caching**: Update cache when new events arrive

**Benefits:**
- Blossom servers now display for ANY user's profile
- Instant display from cache (< 1ms)
- Reactive updates when data changes
- Proper cache hydration for future visits
- Consistent with relay list fetching pattern

**Technical:**
- Imported and integrated blossomServerCache service
- Added cache check before network fetch
- Separated EventStore subscription from network fetch
- Added cache updates on event arrival
