fix: group beIN Sports 1 variants and clarify Laya language warning (#15)

beIN Sports 1 variants stayed separated after projection because
names with region prefixes (C Car, C Reu, Thai), time-shift suffixes
(2h/4h/8h/12h) and language markers (En, Fr, Thai) produced distinct
fingerprints. Extend normalization in the server projection service
and the frontend grouping fallback to fold these into one logical
channel, with tests on the exact reported names. Clarify the Laya
language detection warning so a language-matching failure is not
mistaken for a grouping failure, and bump script versions for cache
refresh.
