Move the emoji selector onto the Alt key top-right corner

Standalone top-row emoji key replaced by a badge in the Alt key key2 swipe slot, drawn as a smile-in-a-circle glyph: new special-font codepoint 0xE01D from Font Awesome face-smile, rebuilt into assets/special_font.ttf with fontforge. Corner slots carry FLAG_SECONDARY so labelColor dims them to secondaryLabelColor; the badge overrides to _theme.labelColor to match the rest of the keyboard labels, and is identified by its codepoint rather than an Event or Kind accessor, because those are only valid for specific kinds and crashed the IME when called unguarded in the draw path. Swipe toward the key top-right to reach it; the config gear stays in the bottom-left. check_layout.output excluded on purpose - unrelated latn_neo2 drift.
