fix: move NotificationsService to parent MatchEventProcessor

[Flegma]

Summary

• Move NotificationsService into the parent MatchEventProcessor constructor so all event processors inherit it
• This fixes this.notifications being undefined in MatchMapStatusEvent, which crashed with TypeError: Cannot read properties of undefined (reading 'sendMatchMapPauseNotification') when a match map entered "Paused" status
• Remove redundant constructors from MatchMapStatusEvent and MatchMapResetRoundEvent to align with sibling event classes

Test plan

• Verify matches can start and progress through map statuses without errors
• Verify pausing a match map triggers the pause notification without crashing
• Verify no regression in other match event processors

so this will also cause moe memory usage, we might want to just add notification service on to the parent class. the request scope means each time it comes into will generate the notification service (new) each time.

TLDR; just add the notification service to the parent

@lukepolo Updated:

• NotificationsService is on the parent class

• No child-level @Injectable decorator - avoids the per-child scope issue he flagged

• Redundant constructors removed from both MatchMapStatusEvent and MatchMapResetRoundEvent, matching the pattern of all the other sibling event classes

• The fix is preserved - this.notifications.sendMatchMapPauseNotification() still works in MatchMapStatusEvent, it just comes from the inherited parent now
