fix(nostr): handle lazy NIP-44 injection in NIP-07 adapter

Updates `js/nostr/adapters/nip07Adapter.js` to unconditionally expose encryption methods (`nip04Encrypt`, `nip44Decrypt`, etc.) and use dynamic property getters for capabilities. This fixes a race condition where the adapter would initialize without NIP-44 support if the browser extension injected the `nip44` API slightly after `window.nostr` became available, preventing encrypted user lists (subscriptions, blocks, hashtags) from loading.
