Feat gnosis omnibridge

[lastperson]

Part of #171

[Copilot]

Pull request overview

Implements support for bridging between Ethereum and Gnosis Chain via the Gnosis Omnibridge, integrating it as a new provider into the on-chain Repayer/Rebalancer flow and adding Gnosis Chain configuration + fork tests (part of #171).

Changes:

• Add GnosisOmnibridgeAdapter and wire Provider.GNOSIS_OMNIBRIDGE into Repayer and Rebalancer.
• Extend domain/provider enums and mappings (Gnosis domain + Stargate endpoint id + chain id).
• Add unit tests, fork tests (Ethereum/Gnosis), config/script updates, and CI wiring for the new fork tests.
