Show the ChatGPT plugin directory listing next to the Claude Directory - #1550

Summary

AnythingMCP Cloud is now listed in OpenAI's ChatGPT Plugin Directory. This shows that listing next to the existing Claude Directory badge, as a trust signal, with the same rule as before: one assistant's listing is never shown to another assistant's users.

• Connecting Claude: Claude Directory badge only.
• Connecting ChatGPT: ChatGPT Plugin Directory badge only.
• Meta Muse: neither (unchanged for Claude, same intent for ChatGPT).
• Any other client, no client, or the trial wall without a known client: both.
• Emails: both.
• Self-hosted: none of these (existing cloud-only checks).

Changes

• Backend OAuth sign-in/consent page (auth-page.ts, login.controller.ts): directoryBadgesFor() replaces showsDirectoryBadge(); directoryBadgeHtml() renders one pill: orange Claude pill, green ChatGPT pill with the inline ChatGPT mark, or a neutral pill with both marks ("Listed in the Claude and ChatGPT directories") so it stays on one line on a phone.
• Cloud email trust band (email-layout.ts): a second pill "Listed in the ChatGPT Plugin Directory" with chatgpt.png (already served at anythingmcp.com/email/, same 32x32 size as claude.png, so no new asset), plus the text-part line. New CHATGPT_DIRECTORY_URL constant.
• Onboarding day-1 and trial win-back help emails: one short "for databases" mention of the ChatGPT Plugin Directory link, Cloud only.
• Demo MCP endpoint anythingmcp_connect_client (ChatGPT): mentions the plugin directory for company databases, like the Claude line mentions the Claude Directory.
• Frontend sign-up trust panel (auth-trust.tsx, login/page.tsx): ChatGPT pill next to the Claude pill, picked by directoryListingsFor() from the client hint. New CHATGPT_DIRECTORY_URL in lib/marketing.ts.
• Trial-end licence wall (trust variant): Claude workspace shows Claude's listing, ChatGPT workspace ChatGPT's, unknown client both; each claim is kept on one line so the trust line breaks between claims.
• MCP server page, ChatGPT tab (Cloud only): "Quickest for company databases: the ChatGPT Plugin Directory" with an "Open in the ChatGPT Plugin Directory" button, above the custom MCP server steps.
• Strings in en, de and it (trust.directoryChatgpt, licenseWall.directoryChatgpt, licenseWall.directoryBoth, mcpServer.chatgptDirectory.*).

Cloud vs self-hosted: every badge and link above is Cloud-only (deployment.isCloud(), ctx.cloud, isCloud); self-hosted behaviour is unchanged.
