Preserve original SQL text in CREATE TRIGGER sqlite_master.sql

Turso reconstructs stored trigger SQL by serializing the AST, which
normalizes all user-provided whitespace. Real SQLite preserves the
original statement text. testColumnWithOnUpdate asserts the stored
text still has its multi-line formatting.

Use the `input` parameter that's already threaded through
translate_inner instead of the AST-reconstructed form.
