- on a string or url field that is not numeric or integer, min and max
compare utf8.RuneCountInString (Laravel's mb_strlen) and answer with
the lagoon::validation min.string / max.string messages
- a min or max argument that is not a whole number is the
unrecognized-rule error, whatever the value
- rule strings without string or url keep their results (pinned by a
test); between is unchanged
- string requires a string value (pointers and named string types
included), url a URL matching Laravel's pattern (urlPattern, shared
with lagoon.ValidateRequest); both skip an empty or blank value
- lagoon::validate.string and .url in the en and pl catalogs, English
fallbacks for a nil translator
- settings saves whose model rules use nullable|string|max:255 or
nullable|url|max:500 no longer fail with an unrecognized-rule error
