chore(setup:db): surface drizzle-kit errors instead of catch-all

push_schema used to print "Failed (may not have db:push script)" for
every non-zero exit, lumping real failures (stuck rename prompts,
pre-existing public enums) in with missing scripts. Now it prints the
real exit code and tails the last 5 lines of drizzle-kit output so the
root cause is visible without re-running by hand.
