[BUG] Action dropdown text and refresh button are clipped in Custom MCP

[ejrtks1020]

Describe the bug

Certain UI elements in the Custom MCP node are being visually clipped:

• The selected action text inside the Available Actions dropdown is truncated when the content exceeds the container's width.
• The refresh icon/button (🔄) next to the dropdown is also partially cut off and not fully visible.

This makes it difficult to verify the full selection or understand available interactions.

To Reproduce

1. Go to a node such as Custom MCP in the Flowise canvas.
2. Set a long-named action in the Available Actions field (e.g., MY_LONG_LONG_LONG_ACTION).
3. Observe the dropdown selection and the refresh icon to the right.
4. Both the text and the refresh button are visually clipped.

Expected behavior

• Action name should either:
  • Show full value on hover via tooltip, or
  • Allow horizontal scroll, or
  • Resize the container dynamically.
• Refresh icon should be fully visible and interactable regardless of text length.
