Upgrade mainnet addresses

[fbac]

Upgrade mainnet addresses and add FireblocksNote.generateNote helper

• Updates several addresses in mainnet.json, including distributionManagerImplementation, payerReportManagerImplementation, and settlement chain admin accounts.
• Adds FireblocksNote.generateNote in FireblocksNote.sol, a pure helper that constructs a note from provided parameters without consulting environment variables.
• Updates BaseAppChainUpgrader and BaseSettlementChainUpgrader to use FireblocksNote.generateNote directly when logging FIREBLOCKS_NOTE_FOR_STEP_2, replacing the previous _getFireblocksNote call.

Approvability

Verdict: Needs human review

This PR updates mainnet production addresses (implementation contracts and admin addresses) which constitutes a significant production infrastructure change. While the script refactoring is minor and the author owns all changed files, mainnet address changes warrant human verification to ensure the new addresses are correct and intentional.
