feat(tracker-web): roadmap submit + email-prompt modals via shared Modal (UX-3.2)

Replace the bespoke local Modal (and its slate/blue/white chrome) with the
shared @bytelyst/ui Modal (Radix dialog — focus-trap/Esc/scroll-lock) for
both the Submit Idea and vote email-prompt dialogs. The dialog titles
become the accessible heading; form fields move to Input/Select/Textarea
and the submit-result message to AlertBanner. Behaviour preserved.
