doc: add a hint to enable PoW defenses to manual hidden services
What changed, and why it matters
This commit only updates documentation. It adds a note in the Tor setup guide suggesting users enable a Tor hidden-service proof-of-work defense if their Tor version supports it. No code behavior changes.
No action required; this is a documentation-only change. Users may optionally review their Tor configuration based on the new guidance.
Security signals we found
No strong security signals were identified.

The directory can be different of course, but virtual port numbers should be equal to
your bitcoind's P2P listen port (8333 by default), and target addresses and ports
