[feature]: UniverseRPC `ACK_ASSET` Server-Streaming RPC

Is your feature request related to a problem? Please describe.
A universe can regularly sync remote federations via global configuration however a client must poll to learn of issuance or transfer updates. More specifically, I would like to proactively mitigate the possibility that user is searching for an asset my node's universe is not aware of.

Describe the solution you'd like
I would like to have server streaming RPCs to be notified when a new asset is first acknowledged by any universe in the maintained federation, being updated with taprpc.GenesisInfo[]. A few cases that would trigger this notification would be:

(1) the issuance event of a new asset
(2) a federation member syncing with a new universe

Describe alternatives you've considered
Polling my universe at some interval greater than the interval the universe is globally configured to sync with federation members, checking for asset_id's that are foreign from the perspective of a client's database. This yields largely wasted attempts.

Additional context
I understand the volume risk of notifications that could be accompanied with such a feature, but the goal is simply to be aware of any asset a user would have interest in... Would greatly appreciate other thoughts, concerns, and approaches!

The issue names the UniverseRPC ACK_ASSET server-streaming RPC and the taprpc.GenesisInfo[] notification payload, but no files or tests. Start by locating the UniverseRPC definitions and existing asset-sync notifications, then determine how issuance and federation-sync events should produce acknowledgements. Done means clients can receive each newly acknowledged asset without polling, with coverage for both described triggers.
