Pontoporeia 053f09b181 fix(migration): deduplicate languages before LOWER() in 025_lowercase_languages.sql
Two rows (Néerlandais id=5, néerlandais id=3) collided when lowercased,
violating the UNIQUE constraint on languages.name.

Added DELETE to keep the lowest-ID row per LOWER(name) group before
the UPDATE SET name = LOWER(name).
