feat(api): Add GET /api/v1/wallet_transactions/:id endpoint

[julienbourdeau]

Context

We have multiple endpoints to get/update wallets and their transactions but an endpoint to get a wallet transaction by id was missing.

Wallets

  POST /wallets
  PUT  /wallets/{lago_id} 
  DEL  /wallets/{lago_id}
  GET  / wallets
  GET  / wallets/{lago_id}
  GET  /wallets/{lago_id}/wallet_transactions

Wallet Transactions

  POST /wallets_transactions
+ GET /wallets_transactions/{lago_id}

Description

This new endpoint allows you to retrieve a wallet transaction.

Alternatively, we could have an endpoint nested under wallet, /wallets/:id/wallet_transactions/:wt_id but I think it's less consistant with our API.

The query in the controller:

SELECT
	"wallet_transactions".*
FROM
	"wallet_transactions"
	INNER JOIN "wallets" ON "wallet_transactions"."wallet_id" = "wallets"."id"
	INNER JOIN "customers" ON "wallets"."customer_id" = "customers"."id"
WHERE
	"customers"."deleted_at" IS NULL
	AND "customers"."organization_id" = 'e3f46553-726d-4948-96be-2eab7a84caab'
	AND "wallet_transactions"."id" = '5186bfda-8d8f-4a32-8ab5-cb0f42c7271d'
LIMIT
	1

Can we also add it to the OpenApi?

Yes, of course 👍
