Tighter buttons, compact alchemy, hero stops beside NPCs

ComicButton defaults shrink ~25% across default and compact size variants, so every button in the app reads tighter. BottomMenu keeps its old 17px label size via a textStyle override, drops the per-slot 80px cap that was clipping the Library label, and constrains the bar at 80% of its parent width so the five tabs stay equal-width.

Alchemy got a compact layout. Owned material count now shows on every card in the left list (not just on the selected plaque). Single-ingredient recipes no longer need a wide panel: the bottom row is an even split between Ingredients (image, name, owned/needed stacked) and Quantity (one row of four stepper buttons + a centred Craft button). The Quantity panel hides entirely when the player can't craft a single unit. Result plaque description caps at 2 lines, drop-shadow added so white text stays legible on every school background. All material descriptions rewritten to fit the new ~48-char two-line slot.

Friend and enemy triggers: tapping one used to walk the hero to the trigger's centre, leaving them visually overlapping the NPC. Now the hero stops at the near edge — left edge if approaching from the left, right edge otherwise — so they end up beside the NPC, not on top. Exit and dialogue/bark triggers (which fire without walking) are unchanged.
