feat(obs-exploration-team): replace title props and wrap EuiButtonIcon with EuiToolTip

[weronikaolejniczak]

Closes #270154

Relates to elastic/eui#9566

Important

These changes should be carefully tested visually by each code owner. Wrapping with EuiToolTip instead of passing title leads to another DOM node and can potentially break the layout. In such cases, I would appreciate committing appropriate fixes to this PR directly, I cannot possibly setup and run all Kibana functionalities to fix every regression.

This PR:

• wraps ALL EuiButtonIcon with EuiToolTip, the content is the same as aria-label, any title passed to EuiButtonIcon is removed,
• changes several title cases (not truncation related) to use EuiToolTip instead (if applicable).
