[#8083] fix: null-safe handling of 'managed' property in CreateFileset.java
(#8144)
### What changes were proposed in this pull request?
In `CreateFileset.java`, the `handle()` method directly called
`properties.get("managed").equals("true")`, which could throw a
`NullPointerException` if the `managed` property was missing.
This PR updates the code to use a null-safe check and defaults to
external mode (`Fileset.Type.EXTERNAL`) when the property is not set.
### Why are the changes needed?
Without this fix, missing `managed` properties could cause NPEs,
breaking fileset creation.
Adding a null-safe check ensures that missing properties are handled
gracefully and the command defaults to external mode.
Fixes #8083
### Does this PR introduce any user-facing change?
No. Valid requests behave the same. Invalid or missing `managed`
properties are now safely handled without throwing exceptions.
### How was this patch tested?
- Manually verified locally that creating filesets without the `managed`
property defaults to external mode.
- Added unit test (or can be added) to ensure that missing `managed`
properties do not cause exceptions.
