Incorrect behavior when both charge and valence are set, leading to inconsistent atom validation

[Zhirnoff]

Steps to Reproduce

1. Open Ketcher and draw any chemical structure.
2. Select an atom and assign both a charge and a valence to it.
3. Observe validation and behavior of the atom's properties on canvas.

Actual behavior

• Both charge and valence are being considered simultaneously, leading to validation errors that are not in line with the expected behavior.
• The atom is underlined incorrectly, indicating an error when the valence is greater than 1, even though the valence should take precedence and resolve the issue.
• This behavior differs from other toolkits that only consider valence if it is explicitly set.

Expected behavior

• When valence is specified, all other parameters (e.g., charge, radicals) should be ignored.
• If only charge is set, the charge should be used in validation.
• If both valence and other parameters (like charge) are set, only valence should be considered, and the validation should reflect that.
