fix(ui): replace native date pickers and tokenize caution colors

Swap the remaining native date inputs (allergy onset, environment
travel/backfill ranges, inbound-document dates) for the app DateField
so they no longer render in the browser's locale order. Route the
medication caution amber and the document info banner through the
warning/info tokens so they adapt to the theme.
