Shuki VakninandLinus Rath c4a7f575c5 feat(accounts): pin default account on top + drag-to-reorder switcher
The account switcher now always renders the default (starred) account first
and lets you drag the remaining accounts into any order. Default stays
pinned; only non-default rows are draggable (shown via a grip handle on
hover). Wraps each row in a draggable container and persists the new order
through the existing reorderAccounts store action.

Ordering logic extracted to pure helpers (sortDefaultFirst,
reorderNonDefaultIds) in account-utils with unit tests.
