OAuth verification, panels, and restore flows for trusted joins.
/verify alt_detection /verify approve /verify builder /verify deny /verify embed_panel /verify embed_result /verify info /verify log /verify mode /verify preview /verify restore_members /verify review /verify role /verify send /verify vpn_block/verify alt_detectionOptional (default OFF): if **ON**, a second *different* Discord account verifying from the same client IP fingerprint as an existing verifier is kicked, DM'd (modern embed), and logged. Stores hashed fingerprints only — bot needs **Kick Members**.
/verify alt_detection <enabled>/verify approveApprove a member pending captcha review and assign the verify role
/verify approve <member>/verify builderOpen live verify panel builder with instant preview (title, description, color, footer, image, thumbnail, button text)
/verify builder/verify denyDeny a pending captcha review (no role); logs and DMs when possible
/verify deny <member>/verify embed_panelQuick-edit verify panel title/description/color (legacy shortcut)
/verify embed_panel <title> <description> [color_hex]/verify embed_resultCustomize titles/colors for verification log embeds (verified / fail)
/verify embed_result <which> <title> <color_hex>/verify infoShow verification mode (OAuth vs captcha), review queue, role, log, OAuth URL
/verify info/verify logStaff channel: one embed per OAuth attempt — **verified** (role outcome + user/device summary) or **failed** (e.g. not in server). Style via `/verify embed_result`.
/verify log [channel]/verify modeChoose **OAuth** (browser) or **DM captcha** (Pillow-generated image in DMs + modal)
/verify mode/verify previewPreview the verification panel and success/failure result embed styles
/verify preview/verify restore_membersRestore verified users: tries to rejoin leavers (OAuth guilds.join token required) and re-apply verify role
/verify restore_members/verify reviewCaptcha: require staff `/verify approve` or `/verify deny` after correct code (needs `/verify log`)
/verify review <enabled>/verify roleSet the member role granted after successful verification (OAuth or DM captcha)
/verify role <role>/verify sendPost the panel: OAuth = link button; captcha = **Verify** button (DM image + code, no external CAPTCHA API)
/verify send <channel>/verify vpn_blockOptional (default OFF): if **ON**, verification checks the visitor IP via ip-api.com (VPN/proxy/datacenter signals). Blocked users see a web message and a fail log embed; no raw IP in Discord. Fails open on API errors; proxy must forward real client IP.
