Introduce trips:share as a dedicated OAuth scope for managing public
share links, decoupled from trips:read and trips:write. Share link
tools (get/create/delete_share_link) now gate on canShareTrips()
instead of the generic read/write scopes. Scope added to both client
and server definitions with full test coverage.
Redesign the consent screen from a narrow single-column card
(max-w-sm) to a two-panel layout (max-w-2xl): app identity and
action buttons on the left, scrollable scope list on the right.
Responsive — stacks vertically on mobile.
