Team page: add entry-year labels, sort by year, roster updates

- Show entry cohort (20XX级) on student cards and alumni rows; sort current students and alumni by year (ascending) then surname; sort-students.js preserves the new year field
- Alumni rows: 3-column layout (name | year | destination) with language-aware name-column width (tight & year-column aligned in zh, wider in en)
- Move 汪燠欣 to faculty (研究助理教授); also list as PhD alumnus (SII)
- Remove 何慷, 李沐宸 from current students
- Mark 6 PhD students graduated → alumni (邵云帆/罗琪/程沁源/吕凯/印张悦/汪燠欣)
- Rename 专任副研究员 → 副研究员 (陈爽, 郑逸宁)
- Fix destinations: 程沁源 (模思智能 CTO), 颜航 (奇绩智峰); move 蒋子恒 masters → undergrad (2013级)
- Bump cache version
