v1.8.0 — Opt-in anonymous usage reports

Added

• Opt-in anonymous usage reports. Nothing is sent until an administrator answers the one-time question (also under Notifications > Privacy). Once a day, from WP cron only, a report keyed by a random install ID (never your site address) goes to prowoos.com with: plugin, WordPress, WooCommerce, and PHP versions and the locale; whether HPOS, the Block Checkout, and Order Attribution are in use; which rules are on and the detection mode; whether Cloudflare or a proxy was detected; and the previous day's event counts. Never emails, IP addresses, order details, URLs, or user data. Withdraw at any time; "Delete my data and stop" asks the receiver to remove everything for your install ID. Full field list in the README under Privacy.
• Daily event counters (30 days): fraud marked by reason, monitor flags, checkouts refused by reason, REST blocks, repeated-failure alerts, auto-bans, bans lifted by hand, "Block this customer" uses, and fraud orders un-marked by an admin.
