Audit DateDmyField required-enforcement (parallel to Pluto PLUTO-10): src/components/form/date-dmy-field.tsx puts required on a HIDDEN input → browsers never constraint-validate it, so required is silently inert. Every caller relying on it for required-date enforcement has a validation gap (only explicit JS/server check actually blocks). 8 caller files in src. Audit each required DateDmyField caller, confirm an explicit check exists, add where missing. Root cause discovered via Pluto práctica DOB empty-date DB error.
