Port various PoB2 buy similar and comparison tab PRs

[vaisest]

Description of the problem being solved:

This PR removes the need to manually generate the URL and reworks the mod matching. Both of these features are ported over from PoB2.

This also contains tradehash fixes for mods.lua. These aren't actually used here now, but they should still be ported over since it will be necessary for the trader, and in general should just be corrected

This ports the following PRs:

• Buy similar: fix mod matching and improve search workflow PathOfBuilding-PoE2#1942
• Buy similar: combine same stats from different mods PathOfBuilding-PoE2#2118
• Fix window title changing in compare tab PathOfBuilding-PoE2#2179
• Add "Buy similar" button to item view PathOfBuilding-PoE2#2193
• Add socket position view to trader and compare tab PathOfBuilding-PoE2#2194
• Refactor buy similar to match by stat descriptors  PathOfBuilding-PoE2#2314
• This also ports the updated mods.lua export script which exports trade hashes properly. This is no longer actually necessary for the buy similar popup, but I'd prefer to keep it here as it'll be useful later anyway.
• Things like the crucible hashes and cluster skill ids won't be used, but are still informative. These can be commented out if it's a problem.
• Above two no longer included as they were really unrelated. The inflated diff line count is due to stat orders changing (QueryMods.lua still has stat orders in the keys here) and due to the TradeSiteStats.lua file being massive.

Steps taken to verify a working solution:

• Lots of manual testing. As far as I can see, most stats should work fine, and the only issues are primarily caused by PoB splitting single stats into multiple mod lines. E.g. PoB parses "Passage" as its own mod line despite it actually being a part of other stats.
• Automated tests ported

Notably, crucible mods aren't matched. This probably doesn't matter much because standard, but regardless in the future it can be added once there's an easier way to match mods. The trade site specifically matches against crucible mods, and not just single stats

This now has all (hopefully) of the PoB2 buy similar stuff. That is, the refactored mod matching, UI which auto generates the URL, and a button for the popup in the items tab

fixed a few small issues but PR looks good to go now
Guessing some of the commented out code in crucible and cluister are for a later PR
