Blossom servers now work exactly like relays:
- App default servers (APP_BLOSSOM_SERVERS) can be toggled on/off
- User's kind 10063 server list is fetched and synced from Nostr
- NostrSync fetches kind 10063 on login and applies it to config
- useInitialSync fetches kind 10063 in parallel on first login
- BlossomSettings UI mirrors RelayListManager with two sections:
App Blossom Servers (with enable toggle) + Your Blossom Servers
- User changes publish a kind 10063 replaceable event to Nostr
- getEffectiveBlossomServers() merges app + user servers like getEffectiveRelays()
- Migration from old blossomServers[] to blossomServerMetadata handled in AppProvider
