Improve tooltips

[gcroci2]

• I implemented tooltips using the DataTable’s tooltip_data feature.
• Initially, I explored using dbc.Tooltip component for greater flexibility. However, dynamically adding a tooltip to each row/column element would require individual element IDs to be passed to the "target" parameter of dbc.Tooltip. After some investigation, I couldn’t find a straightforward way to achieve this, and it seems that DataTable doesn't support such dynamic elements (without embedding some Javascript on the client side).
• The key advantage of dbc.Tooltip is its flexibility, allowing us to embed complex content and enable user interaction, features not supported by the built-in DataTable tooltips. For example, now the tooltips can be displayed but will disappear when the user tries to select and copy text from it. Using something like dbc.Tooltip would solve the issue.
• Another issue with the current tooltips, is that when the data table has multiple pages, the display position of tooltips for the page 2+ is different from the position of the tooltips in the first page.
