- fix parser: capture tr attrs via finditer, strip HTML comments before
cell parse (was leaving '-->' in subject names)
- store class choice in redis: user:{id}:schedule_class (private) and
chat:{id}:schedule_class (groups, admin-only via /setclass)
- /schedule renders day for stored class, /setclass sets it directly
- drop teacher emoji, format grade as "N клас"
