feat!: allow multiple addresses in a single subscription

[mikesposito]

Depends on #9379

Explanation

Currently, AccountActivityService.subscribe only allows a single address per call, forcing multiple subscription when the consumer (also internal ones) need to subscribe to multiple addresses.

This PR changes the subscribe function argument from { address: string } to { addresses: string[] }.
