Move Jerry Tan, Sudeep Pournami, and Wiky Li photos into the Summit2026 folder

These three were placed at the flat static/images/events/ path to match
the literal paths in Olive's source markdown, while every other Summit
2026 speaker photo lives under speakers/Summit2026/. Moving them there
and updating the three img src references makes the photo layout
consistent across all speakers.
