sitehost:phpconfig: patch ini lines in-place, create file/dir if missing

[Copilot]

The original task truncated ps-custom.ini on every run, destroying any unmanaged directives already in the file. It also had no guarantee the file or its parent directory existed.

Changes

• Patch in-place instead of overwriting — for each of the three managed keys (memory_limit, post_max_size, max_execution_time), uses grep+sed -i to update an existing line, or appends if absent
• Create directory and file if missing — preflight mkdir -p … && touch ensures the path exists before patching, even on a fresh container
• Safe value escaping — strtr() for atomic sed-metacharacter escaping (\, |, &) to avoid double-escaping; escapeshellarg() on the echo append path

run('mkdir -p ~/container/config/php/conf.d && touch ' . $ini);
// per key:
run("grep -q '^{$key}=' {$ini}"
    . " && sed -i 's|^{$key}=.*|{$key}={$sedValue}|' {$ini}"
    . " || echo {$key}={$shellValue} >> {$ini}");
