Match center v2: xG race, shot map, attack momentum, weather, officials

The captured FotMob/FIFA/Open-Meteo data becomes visible. Match pages
now carry: a cumulative xG race with goal dots and team totals, a full-
pitch shot map (each side attacking its own end, dots sized by xG,
goals filled), the 90-minute attack-momentum chart, player-of-the-match
with rating, the official info line (stadium · attendance · referee),
and a kickoff-hour weather line for upcoming matches with an altitude
chip above 1,000m. All hand-rolled SVG on the existing token
conventions — design-ready for the upcoming visual overhaul. EN/DE
included, with an honest 'xG and ratings are FotMob estimates' note.
