Remove Matomo node_modules cleanup; tweak SolidTime

Stop removing /opt/matomo/node_modules in Matomo install/upgrade scripts (leave tests removal intact). For SolidTime, set SESSION_SECURE_COOKIE=false and APP_FORCE_HTTPS=false in the generated .env (and append them if missing) to ease non-HTTPS/local installs. Also add a warning message in the SolidTime UI JSON instructing admins to verify new accounts via: php /opt/solidtime/artisan admin:user:verify YOUR@EMAIL.
