When repo is a mirror, and commit author is an external user, then
`GetUserByEmail` will return error.
reproduce/test:
- mirror Gitea to your instance
- disable action and enable it again, this will trigger
`DetectAndHandleSchedules`
ps: also follow #24706, it only fixed normal runs, not scheduled runs.

(cherry picked from commit 69cc79173ddbf7662c4d7246b6161b9351038d16)
Replace #22751
1. only support the default branch in the repository setting.
2. autoload schedule data from the schedule table after starting the
service.
3. support specific syntax like `@yearly`, `@monthly`, `@weekly`,
`@daily`, `@hourly`
