feat(litespeed): make log paths drop-in compatible with cac:phpNN

OLS now writes:
  access -> /home/$user/logs/apache/access_log
  error  -> /home/$user/logs/apache/error_log
  PHP    -> /home/$user/logs/php-fpm/error.log

Matches the cac:phpNN bundled image convention exactly, so existing WHP
log-gathering code (whp-traffic-aggregator.php, process-log-review.php)
works for migrated sites without any panel-side changes. Customer-facing
paths are stable across migrations — "where do I find my access log?"
gets the same answer regardless of image family.

Server-level OLS logs (/usr/local/lsws/logs/) are unchanged — those are
internal diagnostics, not customer-relevant.

PHP error_log is set via a runtime-rendered tiny ini in lsphp's scan dir
(can't be in the static lsphp-overrides.ini because the path is
per-customer).

Customers on the four whp01 migrations (alphaone, peptides, shadowdao,
brain-jar) need a container recreate after CI publishes the new tags.
