fix(migration): add CHECK constraint on text length (defense in depth)

Browse Source 
V18: text column now has CHECK (length(text) <= 10000) to enforce
the 10,000 character limit at the database level, complementing
the application-level enforcement in TranscriptionService.sanitizeText().

Fixes @Nora: "DB constraint catches anything the application misses"
