Fix tor_data/state directory trap + make -notor actually work

1. tor_process.cpp: Auto-recover legacy 'state' subdirectory
   - Old builds created tor_data/state/ as a directory and set
     DataDirectory to point at it. Tor 0.4.9+ rejects this because
     it expects to write a 'state' FILE inside DataDirectory.
   - Fix: Point DataDirectory at tor_data/ itself. On startup,
     if a legacy 'state/' directory exists, migrate contents up
     and remove it.

2. init.cpp: Allow -notor to actually bypass Tor requirement
   - Previously, -notor made StartEmbeddedTor() return false,
     which hit the 'Tor failed to start' error path and killed
     the wallet. Now -notor enables clearnet-only mode for
     diagnostics, benchmarking, and recovery.
   - Updated help text to reflect actual behavior.
