Add Page Token Implementation for Cursor-Based Pagination

[willysoft]

Implement cursor-based pagination in AutoQuery by introducing Page Tokens. This method overcomes the limitations of traditional offset-based pagination, which can lead to inconsistent results due to data changes between requests and suffer from performance issues on large datasets.

Using opaque Page Tokens to represent the cursor position enables efficient and reliable navigation through result sets without relying on OFFSET and LIMIT clauses. The implementation will include generation, encoding, and decoding of these tokens to facilitate seamless paging.

This enhancement provides a scalable and robust pagination mechanism suitable for high-volume and real-time data access scenarios.
