[6.0]: Issues after DUCKDB engine is removed

Reproduce the failure by removing the DUCKDB engine, then inspect resources/templates/database/structure/structure_table_row.twig at line 95 and resources/templates/database/designer/database_tables.twig at line 66. Trace the values passed to those templates and ensure both the database Structure and Designer pages render without exceptions when a removed-engine table remains.

Describe the bug

1. Install DUCKDB engine
2. Create a test table with DUCKB engine

CREATE TABLE sales ( 
            id BIGINT PRIMARY KEY, 
            product VARCHAR(64), 
            amount DECIMAL(12,2), 
            sold_at TIMESTAMP ) ENGINE=DuckDB;

CREATE SEQUENCE primary_key_seq START WITH 1 INCREMENT BY 1 CACHE 100;

3. Remove the DUCKDB engine.

Then:

1. Go to a database (index.php?route=/database/structure&db=ducktest) that contains a DUCKDB table.
2. See error:

Internal error in ./resources/templates/database/structure/structure_table_row.twig#95
Twig\Error\RuntimeError: An exception has been thrown during the rendering of a template ("PhpMyAdmin\Util::formatNumber(): Argument #1 ($value) must be of type string|int|float, null given, called in /usr/share/phpmyadmin/app/cache/twig/2b/2be454f16dd059e8cda1479fd5056017.php on line 241") in "database/structure/structure_table_row.twig" at line 95.

1. Go to a Designer (index.php?route=/database/designer&db=ducktest) of a database that contains a DUCKDB table.
2. See error:

Internal error in ./resources/templates/database/designer/database_tables.twig#66
Twig\Error\RuntimeError: Key "ducktest.sales" for sequence/mapping with keys "ducktest.primary_key_seq" does not exist in "database/designer/database_tables.twig" at line 66.

In 5.2.4-dev there are no errors:
