periodically refresh keys from EKM

[tomholub]

same as FlowCrypt/flowcrypt-ios#841

[DenBond7]

Each time the app starts, if clientConfiguration.usesKeyManager is true, the app should refetch keys from EKM and update the local ones. The fetch should be in the background, not holding up the app during startup.

@tomholub this issue has similar questions to #1375.

Each time the app starts

Could you clarify it?

[tomholub]

Same as here #1375 (comment)

[DenBond7]

One more question. Кespectively to #1168 we have the following

The goal is that if user has keys already configured on EKM and appropriate OrgRules are in place

Should I follow the same behavior? I mean checking appropriate OrgRules. Or Do I need just to check orgRules.usesKeyManager()?

[tomholub]

Good question. At this stage, I think, just check that it usesKeyManager

[DenBond7]

which should show error modal on whichever screen will load next

An example(API error)
