Note

Medium Risk
Version-only changes in this PR, but the ramps-controller release is a major bump that includes documented breaking API removals that can break downstream consumers if not updated.

Overview
Bumps the monorepo version to 830.0.0 and releases @metamask/ramps-controller 10.0.0.

Updates the @metamask/ramps-controller changelog to document breaking API/state removals around quote/widget handling (removes state.quotes/state.widgetUrl, drops fetchQuotesForSelection()/setSelectedQuote(), and replaces quote polling with one-shot fetching), plus a flaky test fix.
