Integrate Tor V3 onion identity into wallet startup, fix freeze

Browse Source 
The wallet was freezing on "Verifying database integrity" because the
old Tor v2 startup code blocked on a mutex (wait_initialized) and
required an onion/hostname file that no longer existed after v2 removal.

Replace the blocking v2 startup with internal V3 onion identity:
- Every wallet now auto-generates Ed25519 keys and a V3 .onion address
- Keys are stored in wallet.dat (encrypted if wallet is encrypted)
- Onion identity is created after wallet loads (Step 8.5) so keys
  persist across restarts
- No external Tor process required for identity generation
- Writes onion/hostname and tor_data/ config for optional external Tor
