As part of this PR, we have added a new field Ignored Reason which will be displayed for all the Ignored Rules. It will give a clear idea about the missing event availability requirement.

Sounds good. But in the actual JFRs there are 5 values of status possible and we will have to create several meaningful messages based on permutation and combinations.
These are the 5 possible values with their meanings:
AVAILABLE(4) : The type has events available in the collection.
ENABLED(3) : The type was actively enabled in the collection.
DISABLED(2) : The type was actively disabled in the collection.
NONE(1) : The type is known in the collection, but no events were found.
UNKNOWN(0) : The type is unknown in the collection.
