fix(signup): make admin-notify recipient env-driven, not hardcoded

Browse source 
The admin signup-notify recipient was hardcoded to
support@screentinker.com and shipped in the open-source code. Combined
with the opt-out SELF_HOSTED gate, any self-hoster who configured their
own Graph credentials but forgot SELF_HOSTED=true would fire their
users' signup PII (email, IP, country) into our support inbox.

Source the recipient from ADMIN_NOTIFY_EMAIL instead, defaulting to
null. When unset, the admin notification is skipped entirely and logged
("[SIGNUP-EMAIL] admin notify skipped (ADMIN_NOTIFY_EMAIL unset)"); the
user's welcome email is unaffected. Hosted prod sets the env var so its
notifications continue; self-hosters send nothing to us by default, and
the .com address no longer ships in code.

Document ADMIN_NOTIFY_EMAIL (and the related mail/self-host vars) in a
new .env.example.
