fix(logpoller): minor patches

[jadepark-dev]

Summary

• Fix replay data model to store fromBlock (uint32) and prevBlock (*BlockIDExt) separately instead of a single requestBlock, fixing off-by-one edge cases in (prev, to] block
  range semantics and enabling block 1 replay
• Add ValidateBlockIDExt to validate RootHash/FileHash lengths (32 bytes) at ingestion and deserialization boundaries
• Harden BOC handling: reject nil log data and detect inconsistent header/payload states
• Fix read-locked replay status access via ReplayStatus() accessor
• Fix test BlockIDExt fixtures to include required RootHash/FileHash fields

Pull request overview

This PR fixes several issues in the logpoller replay mechanism and hardens data validation:

Changes:

• Refactors replay data model to separately track fromBlock and prevBlock instead of a single requestBlock, fixing off-by-one errors and enabling block 1 replay
• Adds ValidateBlockIDExt function to validate RootHash/FileHash are 32 bytes at ingestion and deserialization points
• Hardens BOC handling by rejecting nil log data and detecting inconsistent header/payload states
• Fixes replay status access using ReplayStatus() method instead of direct field access
• Updates test fixtures to include required RootHash/FileHash fields

Nit: I noticed both value and pointer receivers are used for logModel (and filterModel above). The Go convention if any method needs a pointer receiver (state changes), make them all pointer receivers for that type.

This duplicates with integration-tests/logpoller/pg_logs_test.go, could consider moving into testutil package

lgtm, just few minor nits
