fix(data-grid): open dedicated editor for array cells on double-click

[Davydhh]

Problem

Double-clicking a cell whose value is an array (e.g. a Postgres uuid[] /
text[] column) opened the inline <textarea> editor. That editor renders
String(array), cramming the values into a comma-joined string inside a
~120px-tall scrollable box — awkward to read and edit.

The grid was also internally inconsistent: array cells already render as
JSON cells (with the JSON affordance), but editing them fell through to the
plain-text path.

Fix

Route array cells through the same dedicated JSON viewer window that
json/jsonb columns already use on double-click.
