Add cancel confirmation and cancellable statuses

Introduce a unified CANCELLABLE_STATUSES constant and add confirmation UI for cancelling requests. RequestActionsDropdown and RequestCard now show a ConfirmModal before cancelling and use the shared CANCELLABLE_STATUSES to gate cancel actions. The API route imports the constant to enforce server-side validation and uses Prisma.DbNull for selectedTorrent when withdrawing an awaiting-approval request. Tests updated to expect Prisma.DbNull. Improves UX and centralizes cancel logic to avoid duplicated status lists.
