fix(config): hash merged schema cache key to prevent RangeError with many channels

Browse Source 
buildMergedSchemaCacheKey used JSON.stringify as the raw cache key, which
can exceed V8 string limits when 16+ channel schemas are present (each
with full configSchema objects). Replace with a SHA-256 hash of the
serialized JSON.

Fixes #36508
