feat: prefer native database over Docker in sqltest/local

Change the database selection order in local/postgres.go and
local/mysql.go to try native installations first and fall back
to Docker, instead of the previous Docker-first ordering. This
better suits environments where databases are installed natively
(e.g., CI or remote development), avoiding unnecessary Docker
overhead.
