feat(base): extend inline embed scroll viewport leftward, anchor first cell with grid padding

Bring back the leftward extension via negative margin-left so the
scroll viewport reaches AppShell.Main's left edge, then offset the
.grid with padding-left = extendLeft so the first cell still lines
up with page-content on load. The extended area becomes scrollable
empty space the user can pan into — same shape as Notion's inline
databases.

Done with one new CSS var (--embed-grid-pad-left) consumed by the
.grid in grid.module.css. Standalone full-page bases never set the
var, so it's a no-op there.
