What this does

Lets a site reach Central's mailbox sign-in endpoints through its Pilot, so a site on Frappe Cloud V2 can connect a Microsoft 365 mailbox in one click.

• Adds central.api.email_oauth.start and central.api.email_oauth.relay_token to the Central proxy's exact-name allowlist. The browser callback stays off the proxy: the browser goes to Central directly.
• New test: a POST to either method is forwarded to Central with its body.

Testing

• python -m pytest tests/pilot/integrations/test_central_client.py: 28 passed.
• Used by a real Microsoft 365 mailbox connect on a local setup (a V2 site, this Pilot and Central).
