fix: Expedite scheduled push notifications when user switches from online to away/offline

[ceefour]

Proposed changes

Expedite scheduled push notifications when user switches from online to away/offline

Issue(s)

Fixes #19097

How to test or reproduce

1. Android app is online/foreground
2. Kill the app or switch to another app
3. Make sure that user's statusConnection is still online (this is another issue probably for Rocket.Chat.ReactNative how this sometimes can happen, but it does happen and quite easy to reproduce by just using the phone's task killer)
   • Reproducible easily using Samsung A50
   • I also tried using Realme X2 Pro and it's very hard to kill the app without making the app's status go offline. But this works: open Rocket.Chat for Android, turn on airplane mode, kill the app, turn off airplane mode, now Rocket.Chat server user's statusConnection is still online.
4. Server has a posted message, and since user statusConnection is online according to server, meaning push is scheduled in 120 seconds
5. Before message is received by app, and before 120 seconds timed out, user statusConnection is now either offline or away.

New behavior:

6. For documents in NotifcationQueue, will set schedule to now = new Date(), meaning push will be sent soon by worker

I tried to resolve conflict but it seems the API has changed in the latest develop ?

import { UserStatus } from '../../../definition/UserStatus';
import { api } from '../../../server/sdk/api';
