plz check ci

CI failed for database test, I have tested them successfully locally, if unit tests are still unavaiiable, I will remove them.

You may pull mysql docker image in Github workflow to run unit tests.

Please submit the PR to dev branch instead of develop branch.

I should have changed this PR's merge destination to dev before deleting develop branch.

Besides, you may change the database name, username and password to EVENTMESH_DASHBOARD, root and password in config to run unit tests after #32 has accomplished.

I have used eventmesh-dashboard-test as the test database name, is there a specific reason for using EVENTMESH_DASHBOARD? If not, I would edit your ci file.
Also, should the test database host be localhost?

Using - in the database name is not a best practice as it is recommended to use _.

You can try localhost first and see if the application can establish a connection with the container. If it fails, we need to set a MYSQL_ADDR environment variable and use 127.0.0.1 as the MySQL host in GitHub Actions.
