Fix bugs in rerunning jobs (#29955)

Fix #28761
Fix #27884
Fix #28093

## Changes

### Rerun all jobs
When rerun all jobs, status of the jobs with `needs` will be set to
`blocked` instead of `waiting`. Therefore, these jobs will not run until
the required jobs are completed.

### Rerun a single job
When a single job is rerun, its dependents should also be rerun, just
like GitHub does
(https://github.com/go-gitea/gitea/issues/28761#issuecomment-2008620820).
In this case, only the specified job will be set to `waiting`, its
dependents will be set to `blocked` to wait the job.

### Show warning if every job has `needs`
If every job in a workflow has `needs`, all jobs will be blocked and no
job can be run. So I add a warning message.
