fix: if field contains space in constraint expression, checks will fail

[Nordalf]

Description

When adding a constraint to a table, the expression is formatted as: <FIELD> <CONDITION> <VALUE>. If - god forbid - a space occurs in a field name, the condition will not evaluate due to the field name not being escaped. During the enforce_check we are unable to get the field name, and to avoid breaking backward, I am suggesting adding some logic to add backticks to conditions.

1. Get the table schema
2. Loop through schema and check if field exists
3. If field exists, escape with backticks

I am not fan of this solution myself, but I do not have a better solution at the moment.

I am not fan of this solution myself, but I do not have a better solution at the moment.

Maybe we can make it work with just a configuration in datafusion
