Speed up Nostr login and fix list sync, storage unlock, and feed registration

- Remove redundant double signer readiness gate evaluation that added 5-10s
  to the login path (authSessionCoordinator)
- Reduce decryption timeouts (10s→6s per scheme, 3s→1.5s retry delay,
  8s→5s NIP-07 no-prompt, 45s→25s overall ensureLoaded) for faster scheme
  fallback during list sync
- Fix storage tab unlock: remove overly strict capabilities check that
  blocked lazy-injecting NIP-07 extensions, and add auto-unlock attempt
  when profile modal opens with an active signer
- Fix subscription/hashtag decryption: always resolve signer for background
  refreshes (was previously gated behind allowPermissionPrompt), and always
  check window.nostr as fallback decryptor regardless of prompt mode
- Fix capabilities check in subscription decryption: use method existence
  instead of dynamic capabilities getter that returns false during lazy
  extension injection
- Wrap Promise.any decryptor calls in Promise.resolve().then() to catch
  synchronous throws from NIP-07 adapter methods when extension modules
  haven't loaded yet
- Make watch-history feed registration race-safe with pre-check and
  try/catch for concurrent registration attempts
- Improve NIP-07 extension detection with DOMContentLoaded listener for
  faster detection of extensions that inject during page load
