Fix unrelated mods polluting trader searches

[vaisest]

Description of the problem being solved:

This fixes:

• some mods not having weights generated (incr block chance for example). I'm not sure if there are more errors
• querymods generation using tags which are too wide, like "weapon", which caused weapon searches to have a ton of implicits that couldn't actually be on the category
• adding corrupted mods if they have zero weight. I think these might be some standard-only stuff, which might be useful, but PoE1 has so many mods that I don't think filter slots should be wasted on these.

End result: searches should be more relevant. This was mostly done by porting existing PoB2 changes which I believe were made by Quickstick

This is based on #9857 for now

Steps taken to verify a working solution:
