fix(presence-service): set rootDir=../.. to match monorepo dist path structure

entrypoint.sh expects dist/services/presence-service/src/main.js
but without rootDir, tsc infers rootDir=src/ giving dist/main.js.
Setting rootDir=../.. (packages/ level) produces the correct nested path
dist/services/presence-service/src/main.js consistent with other services.
