Subject: [PATCH] fix: manual config not working for ChartJS charts

Move override() to after settings.plugins.tooltip is assigned and
before new Chart(), so manual config is applied last. Also change
$.extend to deep merge so nested plugin options merge rather than
replace, preserving tooltip callbacks.
