fix(config-command): print config values PHP would stringify

`config --list` and `config <key>` rendered a value with `as_string()`,
which yields None for everything but a string, so every int-valued
setting printed as an empty string: `cache-ttl`, `cache-files-ttl` and
the resolved value of `cache-files-maxsize`. PHP builds that output by
concatenating the value into the message, which casts it, so the ports
now go through `php_to_string`.

Two more differences in the same rendering path:

The `[a, b]` branch flattened the array through `as_list()`, which sees
only `PhpMixed::List`, so a keyed array reaching it rendered as `[]`.
PHP takes that branch whenever the first key is numeric, so the values
now come from `array_values_mixed`, which covers both representations.

The raw-vs-resolved comparison deciding between `raw (value)` and
`value` compared the two as strings. PHP compares with `!==`, which
also compares the type: with a `cache-ttl` of `"15552000"` in
composer.json, the raw string and the resolved int are not identical
and Composer prints `15552000 (15552000)`.
