Tighten weather popup layout and add outside-click dismiss

PopupCard now uses HyprlandFocusGrab so any popup in the shell closes
when the user clicks outside it (or any other window in the listed set).
Single primitive — every widget gets it for free.

Weather popup rewritten:
- Smaller cloud glyph beside the city name on one row, both vertically
  centered.
- Condition string flows on its own line and wraps inside the popup.
- Refresh and wttr.in pills sit side by side instead of stacked, no
  more dead vertical space.
- contentHeight tracks the actual content height so the popup is no
  taller than it needs to be.
