feat(projects): improve pagination summary respecting limit and page

[fhverga]

Summary

Improve pagination summary in conviso projects list to correctly respect
custom --limit values and dynamically calculate total pages.

Previously, the CLI relied on the API totalPages value, which may not
accurately reflect custom limits passed via the CLI.

This PR recalculates pagination locally using:

• total_count returned by the API
• current page
• effective limit
• math.ceil() for total page calculation

This guarantees accurate CLI feedback regardless of the API pagination metadata.
