Not adding "Text Match" in Auto-Segment And Refine generates broken syntax

[jtreminio]

Expected Behavior

If you leave "Text Match" empty in the Segment popup what's inserted is:

<segment:,0.6,0.5>

I didn't catch this at first, and when I tried to view the ComfyUI workflow it generated a broken thing:

Will want to add validation:

1. prevent clicking "add" button unless required fields are populated, or
2. do not add to prompt unless required fields are populated, or
3. have a default value in the "Text Match" text field

Additionally, add something to the UI that flags a field as required (Bootstrap has something, or can just use * character)

Actual Behavior

When "Text Match" is left blank, ComfyUI generates a broken workflow.

Steps to Reproduce

Click "Auto Segment Refinement", then click "add" button. See broken prompt:

<segment:,0.6,0.5>

I think this needs two fixes:

• Disable the 'Add' button when there's not valid inputs
• Handle the bad segment input properly serverside (probably just let it emit the empty matching node)
