feat: merge OceanBase picker entries into one with MySQL/Oracle mode toggle

Replace two separate "OceanBase" and "OceanBase Oracle Mode" entries in the
database picker with a single "OceanBase" entry. After selecting, users can
switch between MySQL and Oracle modes via button toggles in the config form.
