Resolve - Display values for links are truncated

Closes #421 (closed)

After the discussion with @marc.hanisch , the displaying values of truncated links issue has been fixed by using the newly implemented ExpandableText component.

In this case, the attachment url is enabled with the mdi-unfold-more-vertical and mdi-unfold-less-vertical buttons for displaying the values.

<ExpandableText v-model="attachment.url" :shorten-at="60" more-icon="mdi-unfold-more-vertical" less-icon="mdi-unfold-less-vertical" />
