[arcoraven]

PR-Codex overview

This PR updates the logic for determining when to resend a transaction in the mine-transaction-worker.ts. It modifies how elapsed time and blocks are calculated and introduces a new condition for resending transactions based on time and block thresholds.

Detailed summary

• Renamed ellapsedMs to elapsedSeconds and changed its calculation.
• Updated log message to reflect the new elapsed time in seconds.
• Changed the condition for resending a transaction to include a check for 120 seconds or minEllapsedBlocksBeforeRetry.
• Renamed ellapsedBlocks to elapsedBlocks for clarity.
