Fix body margin shifting with modals, fix error on project column edit (#30831)

Fixes: https://github.com/go-gitea/gitea/issues/30816, regression from
https://github.com/go-gitea/gitea/pull/30723.
Fixes: https://github.com/go-gitea/gitea/pull/30815, regression from
https://github.com/go-gitea/gitea/pull/30723.

Fomantic [expects a
callback](https://github.com/fomantic/Fomantic-UI/blob/59d9b409879ad9413ea0a3efa4ab2e51017ad9b9/src/definitions/modules/modal.js#L530-L534)
to be called during `hide` which we did not do, so it could never remove
the margin it added to `body`.

I do observe the body content shifting to right by 1px when modal opens,
but this is a bug that existed on v1.21 as well, so not a regression.
