Fix balance notification subscription issue

[atn4z7]

Description

Ticket: CP-9389

when trying to subscribe to the backend, we will skip the logic if the balance notification prompt has not been presented to user. this means users will never receive any notifications. this happens in 2 cases AFAIK:

case 1:

• balance change notification flag is disabled
• user has latest prod build
• user goes to app settings/notifications
• the Allow Push Notifications banner is displayed
• user clicks Open Device Settings
• this will toggle all the switches to ON (even for the ones that are not displayed like the Balance switch)
• balance change notification flag is enabled
• Balance notification switch is displayed with ON value
• user will never receive balance notifications unless he/she toggles the switch to OFF + reopens the app + approves prompt

case 2

• balance change notification flag is disabled
• user has latest prod build
• user goes to app settings/notifications
• balance change notification flag is enabled
• Balance notification switch is displayed with OFF value
• user toggles the Balance notification switch to ON
• user will never receive balance notifications unless he/she toggles the switch to OFF + reopens the app + approves prompt

this pr fixes the above issue by:

• making sure when Open Device Settings is clicked, we only enable all the switches that are displayed to the user at the time
• adjust the subscribe logic to 1/ always run even if balance change notification prompt has not been presented and 2/ only skip it if the Balance notification switch is OFF.

Screenshots/Videos

I did some testing with these scenarios
1/ disable balance notification flag -> install fresh app -> enable balance notification flag -> reopen app -> approve prompt

2/ disable balance notification flag -> install fresh app -> enable balance notification flag -> reopen app -> deny approve prompt -> enable Balance switch

3/ disable balance notification flag -> install fresh app -> enable balance notification flag -> enable Balance switch

Testing

Please make sure 1/ notifications are still working correctly based on user preferences and 2/ production users who are not receiving notifications will start receiving them with this fix
