Render email metadata as real tables and redesign the shell

Browse Source 
Metadata blocks were divs styled with display:table. Nested blocks and
orphan cells created phantom columns that squeezed the value column to
a character or two. Every metadata block is now a real <table>/<tr>/<td>,
which mail clients lay out reliably, and the value column always fills
the remaining width.

The shared shell gets a gradient hero header, timestamp pill, dark
frame, and refreshed section, card, and code-block styling.
