Pull request overview

This PR refactors the anchor block offset configuration and fixes several issues in the preconfirmation system. It converts the hardcoded MIN_ANCHOR_OFFSET constant (previously set to 2) into a configurable parameter with a default value of 1, adds a genesis block edge case fix, and improves error handling and logging in the preconfirmation driver.

Changes:

• Replaced hardcoded MIN_ANCHOR_OFFSET constant with configurable min_anchor_offset parameter (default: 1, previously: 2)
• Added genesis block (block 0) handling in get_anchor_block_id_from_geth to avoid anchor transaction lookup errors
• Refactored post_preconf_requests to accept individual parameters instead of L2BlockV2Payload, improving API clarity and avoiding unnecessary anchor block info fetching
• Enhanced error messages in preconfirmation driver with method names and context
• Adjusted logging levels from debug! to trace! for frequently-called RPC methods
