Admin console - Cannot edit or correctly export large JSONB values (truncation)

# Bug report ## Describe the bug For the past few days, it’s not possible to edit JSONB columns that contain larger amounts of data. The JSON content does not load in the Table Editor/console (even though the “Load” button is shown). What’s worse: when exporting the row to CSV / JSON / SQL, the JSONB column content is truncated, so the exported data is incomplete. This used to work in the past. ## To Reproduce Create a table with a jsonb column. Insert a JSON value larger than ~18,000 characters into that column. Open the row in the Supabase web console / Table Editor. Try to edit the JSONB value (or click the “Load” button). Export the row (CSV / JSON / SQL) from the console. ## Expected behavior Large JSONB values should load correctly in the web console. It should be possible to view and edit the full JSON value (as before). Exports (CSV / JSON / SQL) should include the full JSONB content without truncation. ## Screenshots <img width="357" height="319" alt="Image" src="https://github.com/user-attachments/assets/430cc695-f2fc-48cf-86f7-c04eb3215242" /> If applicable, add screenshots to help explain your problem. ## System information - OS: Windows - Browser Chrome ## Additional context
