[ic-text-field] Setting an IcTextField's value to 'undefined' throws an error in the console

[janfaracik]

Summary of the bug

Setting an IcTextField's value to 'undefined' throws an error in the console. We want to set the value of our input against a prop (that may or may not be there) of a map, but when the prop isn't there an error is thrown from the component due to its value being undefined.

Checking the type for the text field's value field says that it's optional, so I'd expect it to allow for undefined values.

🪜 How to reproduce

1. Add a text field to your page, e.g. <IcTextField name={'test'} label={'test'} value={undefined} />
2. Check the console:

🖥 📱 Device

• Type: Desktop
• Device: MacBook Pro
• OS version: macOS Sequoia
• Browser version: Safari 18.1 (but any browser)

🧐 Expected behaviour

I'd expect undefined to be a valid value for the 'value' property of an IcTextField, and for it to not throw an error in the console.

Additional info

Unsure if this impacts other form components.

A PR would be great. I can fix this, but it's a good first issue. Just do the same changes as in this PR #2182 to check if the textfield prop is undefined. If it is, assign it an empty string
