Operators `>=` and `<=` do not work with ANY and ALL in subquery

[Ev2geny]

Operators >= and <= do not work with ANY and ALL in subquery

Example:

Ledger:

2024-01-01 open Assets:Bank
2024-01-01 open Expenses:Food
2024-01-01 open Expenses:Transport
2024-01-01 open Expenses:Books

2024-01-02 * "Groceries"
  Expenses:Food   40 USD
  Assets:Bank

2024-01-03 * "Groceries"
  Expenses:Food   5 USD
  Assets:Bank

2024-01-05 * "Restaurant"
  Expenses:Food   60 USD
  Assets:Bank

2024-01-09 * "Bus ticket"
  Expenses:Transport  15 USD
  Assets:Bank

2024-01-20 * "Novel"
  Expenses:Books  25 USD
  Assets:Bank

2024-01-22 * "Comic"
  Expenses:Books  10 USD
  Assets:Bank

This query works:

SELECT account, date, number
WHERE account ~ '^Expenses'
AND number > ALL (SELECT number WHERE account ~ 'Expenses:Books')
ORDER BY number

Result:

   account        date     number
-------------  ----------  ------
Expenses:Food  2024-01-02  40    
Expenses:Food  2024-01-05  60   

This one produces an error:

SELECT account, date, number
WHERE account ~ '^Expenses'
AND number >= ALL (SELECT number WHERE account ~ 'Expenses:Books')
ORDER BY number

error: AttributeError: 'EvalQuery' object has no attribute 'dtype'
