[LFX-1157] Fix icon size issue in Connecting Integrations card

[use-tusk]

This PR addresses a UI bug on the dashboard where the integration icons in the Connecting Integrations card were not maintaining a proper square shape when there was a long message next to them. Changes were made to the CSS and HTML structure to ensure that these icons maintain their intended proportions regardless of the length of adjacent messages. The modifications were applied to dashboard-integrations.vue and integration-progress-bar.vue files.
