style(sql): readable contrast for SQL editor identifiers

[c-julin]

What

The SQL editor renders plain identifiers (table/column names like default_redpanda_catalog, cars) with --color-foreground (grey-700 light / grey-200 dark). Against the editor's bg-background surface that reads faint — the bold keywords stand out but the identifier text washes out.

This switches identifiers to --color-strong (grey-900 light / grey-100 dark), the high-contrast primary-text token, so code is clearly readable. Still a semantic theme token (no off-palette literals), so it tracks light/dark automatically.

Change

- { tag: tags.name, color: 'var(--color-foreground)' },
+ { tag: tags.name, color: 'var(--color-strong)' },

One line in sql-editor.tsx's sqlHighlight().
