deploy: reset generated site files before pull (fixes silently-stranded commits)

deploy.sh ran sync_nav.py / gen-service-catalog.py which dirty site/public +
site/src in place; that made 'git pull' abort, so recent commits never reached
prod until pulled manually. Reset those generated paths before pulling so deploys
always fast-forward. Also document the IRP POA signer-name/title follow-up.
