Ranking Source in Roster Column

A small change with outsized quality-of-life impact: the rank column on the Roster page now actually tells you which ranking source it's displaying. Previously, the column header just said "Rank" — leaving you to either remember which source you'd selected, squint at the numbers and try to reverse-engineer it, or simply accept the mystery rankings on faith.

The header now shows the source abbreviation directly — Sleep, FBG, KTC, CBS, and so on — with the full source name revealed on hover. It's the kind of thing you didn't know you needed until you found yourself staring at a rank column wondering if those were dynasty ranks or redraft ranks and whether you should be panicking about your WR3 or not.
