Fixes

cheatsheet toolkit: fixed an oversight that made segmented image-sheets unusable
item-info: fixed an oversight that made class-specific mod highlighting impossible (reported by peterm2024 in #433)
map-info: the x% increased magic monsters mod didn't show because it was changed from more to increased in 3.25

updated unique drop-tiers to poeladder's current data
added mod and item tags to the database to avoid mixing up affixes between item-classes
- this is only relevant if ilvl-requirements are being displayed
- example: belts can roll the "encased" (ilvl 83) and "enveloped" (ilvl 86) armor prefixes, and body armors can also roll "encased" (ilvl 43) and "enveloped" (ilvl 51)
- previously, when checking a body armor with one of these mods, it would always display ilvl 8X as the mod requirement
changed the level-ranges for ilvl highlighting from 52-83 to 10-80
- with the recently-buffed life rolls, it didn't make sense to highlight life-values around 100 in red
