Review Comment:
   [P2] Render expressions as bounded code while preserving SQL formatting
   
   At a 1512×861 viewport, a persisted metric containing a long SQL string 
literal overflows its 274px Expression cell (scrollWidth 644px), paints over 
Description, and is clipped at the table edge. This inline span also collapses 
explicit newlines, so text following a `--` comment appears to be part of that 
comment. Please constrain each dialect's code block, preserve line breaks, and 
either wrap long tokens or scroll within the cell. Both metrics and expanded 
fields use this renderer.

Review Comment:
   [P2] Keep the detail tables readable in shorter desktop windows
   
   At a 1280×600 viewport, `calc(100vh - 37rem)` limits the table body to 8px. 
With the existing four-metric example, only the header and pagination are 
readable; scrolling the outer panel cannot reveal the rows because the inner 
body stays clamped. Even at 720px high, its 128px body cannot show one complete 
four-dialect metric. Please give the body a usable minimum height or let the 
outer panel handle vertical scrolling, and apply the same fix to the Datasets 
and Relationships tables.
