Add VAA enqueued status in vaas and/or transactions collections

[SamantaCasal]

Description:

As a user, I want to see if a VAA is enqueued when I access the endpoints api/v1/vaa?TxHash or api/v1/transactions/vaaId, so I can determine its status directly from these endpoints and show it in the wormholescan UI with On Hold status

Current behavior:

At present, the endpoint utilized for displaying transaction details lacks information about enqueued VAA. Consequently, some transactions that are actually in the governor queue are mistakenly shown as "complete."

Acceptance Criteria

When I make a request using any of the following endpoints:

• api/v1/vaas?txHash
• api/v1/vaa/chainId/Emitter/sequence
• api/v1/transactions/chainId/emitter/sequence

I should be able to view information regarding whether the VAA is enqueued. If there's a status available, it should clearly indicate "On Hold" or another status predefined by the product area.

Evidence:

In wormholescan

Response governor endpoint about the same transaction:

Transaction endpoint response: HERE

Vaas endpoints responses: SearchByVAAID

SearchByTxHash

we are going to handle this for the api v2
