Move category and high_priority to payload classes

Use polymorphism instead of case statements in Native push target:
- DefaultPayload#category returns "default", #high_priority? returns false
- EventPayload#category returns "assignment"/"comment"/"card" based on action
- MentionPayload#category returns "mention", #high_priority? returns true

This simplifies the Native push target by delegating source-specific
logic to the appropriate payload classes.
