improve diagnostics, security UX, and network tab refresh

Diagnostics & logging:
- add verbose logging system (VERBOSE_LOGF) with toggle in Settings
- forward app-level log messages to Console tab for in-UI visibility
- add detailed connection attempt logging (attempt #, daemon state,
  config paths, auth failures, port owner identification)
- detect HTTP 401 auth failures and show actionable error messages
- identify port owner process (PID + name) on both Linux and Windows
- demote noisy acrylic/shader traces from DEBUG_LOGF to VERBOSE_LOGF
- persist verbose_logging preference in settings.json
- link iphlpapi on Windows for GetExtendedTcpTable

Security & encryption:
- update local encryption state immediately after encryptwallet RPC
  so Settings reflects the change before daemon restarts
- show notifications for encrypt success/failure and PIN skip
- use dedicated RPC client for z_importwallet during decrypt flow
  to avoid blocking main rpc_ curl_mutex (which starved peer/tx refresh)
- force full state refresh (addresses, transactions, peers) after
  successful wallet import

Network tab:
- redesign peers refresh button as glass-panel with icon + label,
  matching the mining button style
- add spinning arc animation while peer data is loading
  (peer_refresh_in_progress_ atomic flag set/cleared in refreshPeerInfo)
- prevent double-click spam during refresh
- add refresh-button size to ui.toml

Other:
- use fast_rpc_ for rescan polling to avoid blocking on main rpc_
- enable DRAGONX_DEBUG in all build configs (was debug-only)
- setup.sh: pull latest xmrig-hac when repo already exists
