Call processAllAssertionsInRange with small batch filterOpts

ProcessAllAssertionsInRange is called in two scenarios:

1. During startup — when the system processes from the last confirmed assertion to the latest block.

   • This case was already handled by splitting the getLogs query into smaller batch FilterOpts to avoid exceeding the block limit.

2. During regular polling — when the system polls at a configured interval.

   • The assumption was that regular polling would naturally limit the batch size. However, since the polling interval is configurable, the block range could still exceed the limit.

This PR ensures that even during the polling flow, getLogs queries are broken down into smaller batch FilterOpts, preventing potential block limit issues in both scenarios.

LGTM, but fails build.
