feat(backup): zip and rotate uploads for inventory/sirh/lesstime

Aligns the repo with the version that was running in prod.
Adds INVENTORY/SIRH/LESSTIME_DOCS_DIR variables, zips each upload
directory next to the DB dumps, keeps the 3 most recent zips, and
splits the Discord summary into BDD/Documents sections.
