   ## Description
   
   When migrating a Superset instance from SQLite to PostgreSQL, very long 
database error messages can overflow the UI.
   
   In the current behavior, long error strings:
   
   - Extend beyond the visible container
   - Are hard to read in full
   - Make copy & paste difficult, especially when debugging or sharing the 
error externally
   
   This becomes particularly problematic during database migrations, where 
database errors are often verbose and need to be copied verbatim for 
troubleshooting.
   
   ## Design input
   
   No specific design input required at this stage.
   
   This is primarily a usability issue. The expectation is simply that long 
error messages are rendered in a way that remains readable and easy to copy 
(e.g. wrapping or scrolling), consistent with existing Superset UI patterns.
   
   ## Steps to reproduce
   
   1. Migrate an existing Superset metadata database from SQLite to PostgreSQL
   2. Start Superset and trigger database initialization or validation
   3. Ensure a schema mismatch exists (for example, a foreign key constraint 
where column types differ, such as string vs uint)
