Include parentName and isLatest in alert notification limitations for better grouping across project versions

### Current Behavior

Alert notifications in Dependency-Track can currently be limited by:
- A specific project-version combination
- Specific tags

However, there is no support for parentName in the alert notification system.

In my use case, I structure multiple projects so that:
- Each version of a logical application is a separate project (basically the same projectName + a new version number).
- These projects are grouped under the same parentName (the projectName itself, I have some exceptions where the parentName is not the projectName as it contains multiple projects).
- The latest version is marked with the isLatest flag.

This approach allows me to logically manage versioned software. But without parentName in alert notifications, I cannot:
- Correlate issues across different versions
- Limit or prioritize alerts only to the isLatest version
- Aggregate alerts by logical application group

### Proposed Behavior

Include parentName in the alert notification "Limit To" options:
- Allow alert notification scoping by parentNam and isLatest flag, in addition to existing project/version and tags.

This would:

- Enable grouping alerts across versions under the same logical project
- Allow to route alerts more intelligently, e.g., only for latest active versions
- Help focus on what matters operationally
