chore: disable OPcache for dev and mount php.ini as volume

opcache.validate_timestamps=0 caused stale bytecode after code changes —
containers needed a full restart to pick up edits. For dev, OPcache is now
disabled entirely. php.ini is mounted as a volume in all app services so
config changes take effect with a simple `docker compose up -d`, no rebuild.
