remove global styling for MUI components

[lennczar]

TextField styling on the DAO page is different from the styling we use on the App page, this is fine so long the styling on the App page is not affected. However, CSS rules introduced in settings-editor-amendments in src/app/global.scss do affect it.

Example: fields of UnitField are no longer the same height

Please remove these rules and move them to local styling:

.MuiCheckbox-root {
    .MuiSvgIcon-root {
        width: size.$large-text;
        height: size.$large-text;
    }
}

.MuiTextField-root {
    .MuiInputLabel-root,
    .MuiInputBase-root {
        font-size: size.$text;

        input {
            padding: calc(size.$gap * 0.4) calc(size.$gap * 0.6);
            font-size: size.$text;
        }

        fieldset {
            border-radius: size.$task-radius;
        }
    }
}
