docs: deploy artifacts for the monerogue.app stagenet instance

Prepared (not executed) artifacts for the two-instance deployment:
- scripts/deploy/monero-wallet-rpc.service: Monero STAGENET wallet-rpc unit
  (mirrors wownero-wallet-rpc; binds 127.0.0.1:38083, daemon :38081, password
  placeholder).
- scripts/deploy/monerogue.service: second game instance unit (separate
  user/dir/DB, :3001).
- docs/DEPLOY_INSTANCES.md: full runbook for both instances — mainnet
  reconfigured to free-to-play + NO payouts, and the new Monero stagenet
  instance with payouts ON; includes the monerogue .env and verification.

No server changes and no secrets committed (placeholders only).

+# Wallet:  /home/jw/Programs/monero-x86_64-linux-gnu-v0.18.4.4/test  (the stagenet wallet with coins)
+# Daemon:  monerod --stagenet RPC on 127.0.0.1:38081 (already running)
+# RPC:     binds :38083 (free)

+# IMPORTANT: replace REPLACE_WITH_WALLET_PASSWORD below with the wallet's real password
+# (do NOT commit the real password). Consider --wallet-dir + --rpc-login for production,
+# but this mirrors the existing wownero setup for parity.
