hack/dao: `gf gen dao` merged same name tables in multi-schemas

[aitimate]

Go version

go version go1.23.2 windows/amd64

GoFrame version

2.8.0

Can this bug be reproduced with the latest release?

Option No

What did you do?

	gf gen dao

What did you see happen?

gf gen dao merged the fields of tables with the same name across multiple schemas in my PostgreSQL database into a single table, causing all subsequent DAO operations to fail. (POSTGRESS)

What did you expect to see?

I would like to restrict the schema name, such as adding a configuration to prefix it with public.
