Poc smoke tests

[Hakob23]

Description

Adds optional Flyover smoke tests to RIT to validate split-contract deployments against a running Liquidity Provider Service (LPS) on regtest.

This is a POC to exercise end-to-end LPS wiring without extending the existing on-chain Flyover peg-in test suite (01_04_*).

Motivation

After deploying Flyover split contracts (pegin, pegout, discovery, collateral management) and starting LPS locally, there was no lightweight way to confirm:

1. LPS health and provider discovery
2. Quote retrieval and acceptance over HTTP
3. The same flow via @rsksmart/flyover-sdk

These tests are opt-in: when required env vars are unset, they skip automatically so default RIT CI is unaffected.

Changes

• Add tests/01_08_00-flyover_split_contracts_smoke.js — LPS HTTP flow (/health → /getProviders → /pegin/getQuote → /pegin/acceptQuote)
• Add tests/01_08_01-flyover_sdk_smoke.js — same flow via @rsksmart/flyover-sdk
• Add lib/flyover-smoke-test-utils.js — shared env checks, contract bytecode validation, quote building, HTTP helpers, and SDK shim
• Add config/regtest-external-lps-smoke.js — RIT config for external regtest stack (pre-running RSK node, bitcoind, LPS)
• Add dependencies: @rsksmart/bridges-core-sdk@0.6.0, @rsksmart/flyover-sdk@1.9.0 (pinned versions)
• Document setup in README.md and .env-example

Testing

Local smoke test run (verified)

Prerequisites:

• RSK regtest node at http://127.0.0.1:4444
• LPS at http://127.0.0.1:8080
• Deployed split-contract proxy addresses on that chain (from liquidity-bridge-contract/broadcast/DeployFlyover.s.sol/33/run-latest.json)
