feat(auth): GitHub OAuth login + SMS one-time-code login
GitHub: /v1/auth/github + /callback — authorization-code flow, fetches
the verified primary email via /user/emails, reuses upsertOAuthLogin.

SMS: phone is now a first-class login identity.
- schema: users.email nullable, users.phone added, new sms_codes table.
- @bmm/auth: issueSmsCode / consumeSmsCode — 6-digit code, hashed at
  rest, 10-min TTL, per-phone rate limit, 5-attempt cap, get-or-create
  user by phone.
- apps/api: /v1/auth/sms/request + /verify, Twilio REST send (no SDK),
  per-IP throttle. /v1/auth/providers now reports google/github/sms.
- login UI: Google + GitHub buttons, Email|Phone toggle, two-step SMS
  (number -> 6-digit code with one-time-code autofill).

SMS link was rejected in favour of an OTP code — carrier link-scanners
consume magic-link tokens before the user taps them.
