Subject: [PATCH 3/3] Fix AI combustion research page and post structure

- Fix Liquid syntax error in ai-combustion.md (simplify to plain where filter)
- Add intermediate listing page at /research/ai-combustion/ by moving post permalink to /research/ai-combustion/hosvd-gpr-surrogate/
- Switch post layout to post and add date for "Posted on" display
- Remove Contributors section from research post (contributors belong in software/Apps)
