feat(sales): redirect beta-signup to /register; queue waitlist emails

Phase 2 retires the public beta-signup form in favor of the self-serve
register flow. The /api/v1/beta-signup POST endpoint stays mounted but
now responds with 307 to /register?from=beta so any external links keep
working and analytics can tag signup origin via the from query param.

Note: there is no beta_signup table in the schema — the original
endpoint only fired an email notification, so there is no waitlist to
read and no migration to run for the email-sent_at field. The one-off
admin script in the spec is therefore a no-op and is intentionally not
added here.

- Replace POST /beta-signup handler with RedirectResponse(307)
- Drop the EmailService.send_beta_signup_notification call (the user is
  now redirected into the register flow, which has its own email path)
- Add tests/test_beta_signup_redirect.py covering the 307 + Location
