Change read duration total to include all history

[nzoba]

Just saw that the total read duration doesn't include all history, just the manga in library, so I changed that

And some visual changes:

• tweaked a bit the general stats in case there is a language with long words and to avoid setting the number of lines
• reorganized the stats to have more homogeneous description lines (not sure which is better between vertical centered or top, let me know if you have a preference)
• added tooltips for read duration and mean score
• converted the link to stats details to a button
• fixed the status distribution wrapping when the text + value are too long (wrap the description text instead of value now)

Also tweaked the details stats order to put the read duration higher

I'll likely just update the wording on "Mean score" but this works for now
