Experience Collection

This ticket encompasses a few steps to accomplish for a minimal buildout of the experience collection button

• [x] population: session.mjs
  • [x] save livedExperience
  • [x] do not auto-replay saved livedExperience
• [x] structure: develop frontend-relevant version of livedExperience collection depiction, will be different from story, for instance
  • { being, completed, experience_date, experience_id, id, mbr_id, title, variables, }
• [x] pipeline
  • [x] frontend: getCollections(type=experience)
  • [x] frontend: mechanic for closing collections
  • [x] backend: should work through collection scheme down to being=lived-experience
  • [x] experienceEnd should determine whether complete or incomplete experience
