refactor(style): type SymfonyStyle messages as strings and cells

SymfonyStyle modelled PHP's string|array message parameters, its array of
listing elements and its table headers/rows as PhpMixed, then normalised
and stringified them at every entry point. Take &[String] for the message
and listing parameters, Vec<Cell>/Vec<Row> for table (matching the
horizontal_table signature) and Vec<String> for the choice options, so the
is_array/is_iterable normalisation and the php_string helper both go away.

PhpMixed stays where PHP is genuinely mixed: the question answers returned
by ask/ask_hidden/choice, their validators, choice's string|int|null
default, and the progress_iterate elements.
