feat(lolschedule): add LoL esports match schedule module

New module exposing /lol_today and /lol_week commands, backed by the
Leaguepedia Cargo API (MatchSchedule table). Renders scores for
played/live matches and ICT times for scheduled ones. Caches range
queries in KV (60s today, 300s week) with stale-fallback on fetch error.
