feat(debug): copy repo fonts into zip project and append font overrides so theme uses ./fonts; fix DejaVu fallback issue

fix(fonts): add font fallbacks in template; patch theme file inside uploaded/repo zip during debug compile when needed

revert(template): restore original beamerthemegemini.sty (remove font fallbacks); rely on font install in postBuild instead

build(space): install fonts-raleway and fonts-lato in postBuild to satisfy fontspec without modifying template
