feat: standard bridge contract improvements

[shaspitz]

• Removes usage of custom mint/burn precompiles in whitelist contract, in favor of funding whitelist contract directly on genesis with receiver func. See https://github.com/primevprotocol/mev-commit-geth/commit/5b1843e05a0610688ffbdaa16dcf897d8a08583e. This change has made interactions with whitelist contract more reliable and easier to test.
• Makes additional bridge event fields indexed for more efficient client side querying
• Adds transferFinalizedIdx to the gateway contracts to assert on-chain that messages are relayed FIFO and cannot be censored
• Adds further testing to bridge contracts including interactions w/ whitelist
• Changes expected contract addresses due to bytecode changes
