feat: trade query — local mods, crafted slot filters, corrupted filter, UI layout

- Fix local weapon/armour mods mapping to wrong trade stat ID (preferLocal lookup)
- Fix crafted mod count group using wrong data pool (data.masterMods vs data.itemMods.Item)
- Fix crafted slot stat IDs: looked up dynamically from trade API, cached in PseudoStats.lua
- Add Implicit Mods, Pseudo Mods checkboxes; rename Corrupted Mods → Corrupted Items
- Corrupted Items now adds misc_filters exclusion same as Mirrored Items
- Fix control layout: all controls left-aligned in single TOPLEFT chain, correct order
