Allow empty table views

[saintmatthieu]

Needed for Audacity PR audacity/audacity#10649

• Allow empty table views: Audacity's plugin manager has filters that may yield no match. In that case, the displayed table should be empty.
• Bubble up horizontal-header click: so that table views can react to those clicks, here to order the table rows after the clicked column, like is standard behavior.
• expose displayTruncatedTextOnHover property of StyledTableView: in lieu of tooltips

• I signed the CLA
• The title of the PR describes the problem it addresses

• I created a unit test or vtest to verify the changes I made (if applicable)

📝 Walkthrough

Walkthrough

This pull request introduces truncated-text-on-hover display capability to table views by adding a new displayTruncatedTextOnHover property that cascades from the main StyledTableView component through to individual table cells. Additionally, a new horizontalHeaderClicked signal is introduced to emit column index events when horizontal headers are clicked. The changes also modify the table model's setTable method to process empty table updates instead of ignoring them through early returns.
