feat: render SQL initial/result data as tables in a two-pane layout

Rewrites Content.vue to give the SQL language its own top/bottom split
(code editor over data tables) instead of sharing the horizontal
left/right layout used by other languages. SqlSection.vue now renders
the preset data and the post-run result as two side-by-side
n-data-tables, falling back to the existing error UI when a run fails.

Also registers NDataTable globally in main.ts (naive-ui components must
be explicitly registered via create()); without it n-data-table was an
inert unresolved custom element and no rows rendered.
