Find alternative to vaul bottom sheet (drawer) component

[tom-sherman]

Vaul was added in #289 but is unmaintained, we should find an alternative

Either we find a decent alternative (preferred) or fork to fix the problems with it (I'll list these below when I get time).

Problems with vaul

• The close component doesn't trigger exit animations
• It uses @radix-ui/react-dialog and not radix-ui package
• It has bugs when used with <React.Activity> (this will be very obvious if we ever adopt next.js cache components as previous routes in bfcache are hidden Acitivtys)

I started a discussion in shadcn-ui to ask what the plan was too, since maybe this will be done for us shadcn-ui/ui#8982

Replaced with our own fork https://github.com/frontpagefyi/weasel in #289
