✨ payments service: implementation of apis and db repos for one-time-payment workflow ⚠️

[pcrespov]

What do these changes do?

This PR takes the logic for the one-time-payment workflow presently in web-server's payments plugin and adapts it into the payments service. The modules affected are highlighted with arrows in the drawing above. Some details follow:

• ✨ db: Implements db repository to annotate transactions for the one-time-payment workflow
  • services/postgres used to setup engine to postgres service
  • models/db are pydantic models to handle database data
• ✨ api/rpc: implements init_payment by annotating initiated transaction using the repository above
• ✨ api/rest: implements acknowledge_payment annotated ack transaction using the repository above
• ♻️ ✨ Misc
  • Drafted some error handling (will be completed in subsequent PRs)
    • see starlette note on exceptions vs errors: https://www.starlette.io/exceptions/
    • handlers to convert status errors into API error model: DefaultApiError
  • updated scripts/fake_payments_gateway to match openapi specs provided by our partners
  • new fixtures and new tests (coverage right now at 94%)

Note that after this PR, the payments service will still not be full operational to perform a complete the one-time-payment. For that still needs:

• the rpc client on web-server's payments plugin side (next PR)
• the socketio to trigger events from the payments service to the front-end (not relevant for the moment)
