Description

• It fixes !46805
• Here is a brief description of what this PR does

Yes/No default values were typed as free text (e.g. Non). Since #1254 applies default values on creation, this breaks item creation on strict SQL mode:

Incorrect integer value: 'Non' for column ...

• Normalize Yes/No default value to 0/1 (getter, add/update, migration)
• Use a Yes/No dropdown to configure the default value
• Add ContainerTest::testYesNoDefaultValueIsNormalized
