ChatbotWelcomePrompt: long prompt title and message overflow suggestion cards #910

Description

When ChatbotWelcomePrompt renders welcome/suggested prompt cards with long title or message values, the text overflows horizontally outside the card boundary instead of truncating.

This is especially visible when consumers pass user-generated content (e.g. saved prompts with long names and bodies) as prompts[].title and prompts[].message.

Steps to reproduce

1. Render ChatbotWelcomePrompt with a prompt like:

<ChatbotWelcomePrompt
  title="Hello"
  description="How can I help?"
  prompts={[
    {
      title: 'aDSFGGEWRTYUIOPASDFGHJKLZXCVBNMQWERTYUIOPASDFGHJKLZXCVBNM',
      message: 'QEWRETRTDYUIOPASDFGHJKLZXCVBNMQWERTYUIOPASDFGHJKLZXCVBNMQWERTY',
      onClick: () => {},
    },
  ]}
/>

2. Observe the card title and body text extend past the card border.

Expected behavior

• Prompt card title should truncate with ellipsis (single line).

• Prompt card message/body should clamp to a reasonable number of lines (e.g. 2) with ellipsis.

Actual behavior

Title and message render as unbroken single-line strings that overflow the card container.

Component / version

• Component: ChatbotWelcomePrompt (pf-chatbot__prompt-suggestion cards)

• @patternfly/chatbot version observed: 6.9.0-prerelease.2

Suggested fix

Apply truncation styles in ChatbotWelcomePrompt (or underlying PF CardTitle / CardBody usage), e.g.:

• CardTitle: overflow: hidden; text-overflow: ellipsis; white-space: nowrap

• CardBody: multi-line clamp (-webkit-line-clamp: 2) for message

Optionally expose props to control clamp line count.

Workaround

Consumers currently override via CSS targeting .pf-chatbot__prompt-suggestion .pf-v6-c-card__title and .pf-v6-c-card__body.
