When npm run create-user is invoked from Windows Git Bash with
single-quoted values (--password 'foo' --name 'Berwn'), the quotes
survive into process.argv and end up stored in the DB. Login fails
silently because the stored hash is for 'foo' but the user types foo.
create-user and diag-user now strip a single set of matching surrounding
quotes from every --flag value. Real values that need literal leading
and trailing quotes can be escaped.
diag-user prints the full user row (email, normalized email, hash
prefix, isActive, memberships, session count) and optionally verifies a
password. Useful whenever a login mystery shows up.
