fix(config): stringify cache-files-maxsize like PHP's (string) cast

Config::get() resolves cache-files-maxsize by matching the stored value
against a size regex. The port read that value with as_string(), which
yields None for anything that is not a string, where PHP casts with
(string).

create-project feeds Config::all() back through Config::merge(), so the
second read finds the byte count the first read produced rather than the
original "300MiB". as_string() then yields an empty string, the regex
fails, and the resulting RuntimeException is swallowed by Config::get(),
which maps Err to null. FileDownloader turns that null into a zero max
size via .as_int().unwrap_or(0), and Cache::gc() deletes every file in
the download cache because the total always exceeds zero.

Apply the same cast on the path branch, the other site where Config.php
writes (string).
