[Feature]: Loot history boss/encounter filter dropdown

[Xerrion]

Problem / Motivation

Loot history currently shows all items in a flat list. In raids with multiple bosses, it is hard to find items from a specific encounter. Blizzard's Loot Rolls panel has a boss dropdown filter.

Proposed Solution

Add a dropdown at the top of the history frame to filter entries by boss/encounter name. Could also add a separate tab or section divider for raid vs party loot.

new update is working great settings upgrade is huge, didnt know if should make whole post but since this would be replacing blizzards loot window with your better loot history version a way to suppress the window that opens with /loot from auto opening would be good. need to do some more checks im unsure what actually makes it show outside of /loot command and end up having both your and blizzard on the screen. also if the history could persist after entering or leaving instances so if you want to look back on rolls from a raid or two ago you can. (ignore if this happens already? havent tested enough yet)

Thanks for the kind words, really glad the settings upgrade landed well!

On the double-window issue - I looked into this and there is a real timing gap when the Blizzard loot frame is delivered by a late-loading addon. I have opened #103 to track and fix it properly. Good catch.

On history persistence: you are right that history does not currently survive a session end or relog - it is seeded from the game's own C_LootHistory API each time, which only covers the current session. I have opened #104 to track adding proper persistence so you can look back at rolls from previous sessions.
