Fix Home tab layout: switch to panel mode for full-width flow card

The flow card was squeezed into a narrow masonry column on desktop,
making it hard to read. Switch Home tab from masonry to panel layout
(matching all other tabs) so the flow card gets full page width.

Also: move solar summary + weather into horizontal-stack side-by-side,
remove standalone weather card (now part of the h-stack).
