The API currently does not respect the documentation when returning a
person's birthDate. The doc/swagger says it will be of "YYYY-MM-DD"
format but the string is a full ISO8601-with-tz string. This causes
issue #16216 because the <input> tag is strict about supported value
formats.
I believe this was introduced by #15242 which switched some queries from
TypeORM to Kysely for the person repository. TypeORM does not parse
date, but our Kysely configuration does (explicitely).
This commits updates the types to represent both possibilities and ensure
the API always returns the correct format.
