History / Training for Portal Users Developer Guide

LMS: training for portal users, and people groups Four new pages -- a user guide and a developer guide for each of: People Groups the shared groups on Tickets -> Users Training for Portal Users the four assignment targets, what a portal user sees, deadlines, and reminder emails The developer guides carry the parts that would otherwise be rediscovered: the (learner_type, learner_id) key and why nullable was not enough, the three silent traps in the db_verify migration, the two-identities-in-one- session problem and the as=portal fix, and why knowledge_user_groups must not be renamed. Corrected in passing: LMS.md opened by saying courses are 'assigned to learning groups, taken by analysts', which stopped being true; its assignments section and key-tables list are updated with it. Self-Service Portal gains a Training section. Sidebar updated.
