solicitar-acceso/actions.ts:84 CREATE path stores normalizeEmail(rawEmail) into BOTH email + normalizedEmail columns — email col gets normalized value (should be raw); sibling of MARS-536

Flagged by coder during MARS-536. The access-request CREATE path solicitar-acceso/actions.ts line 84 sets a var email = normalizeEmail(rawEmail) then INSERT binds [email, email] into (email, normalizedEmail) — identical corruption to what MARS-536 fixed on the completar path: the email column gets the normalized value when it should hold the raw email. Leaves users.email / accessRequests.email untrustworthy from the create path. Fix = same trivial split: store rawEmail in the email column, normalizeEmail(rawEmail) in normalizedEmail, matching callback/route.ts:171 + users-actions.ts:484. Class-S.
