Rebrand org identity: AISViz -> MAPS Lab

[gabrielspadon]

Community-health + README updates for the org rename. Org-voice identity (organization, team, community, landing page, contributing) moves to MAPS Lab; org URLs repointed to github.com/MAPS-Lab (folding the AISdb-* repo renames); security/CoC/contributing contact -> mapslab@dal.ca. Product references (the AISViz product line, aisviz.cs.dal.ca, aisviz.gitbook.io) intentionally kept.
