Add four animated KonoSuba ESPHome pages
Megumin's daily explosion, the Adventurers' Guild quest board (agenda, weather, solar), Megumin's adventurer card and a party battle against a giant toad with a live-data battle log. Original 1-bit pixel art lives in tools/konosuba_sprites.py, which generates konosuba_sprites.h and can render a preview PNG. Home data and drawing helpers shared by the themed pages move to el512_pages.h; the display gains dither_mask() for a dissolve-in intro. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
