fix(slack): return one conversation page with next cursor

[TheodoreSpeaks]

Summary

• Stop auto-pagination in Slack v2 List Channels to avoid bursts of API requests. Each call returns one page with nextCursor and hasMore so callers can request the next page explicitly.
• Remove Max Pages and the redundant pages output, migrate saved settings, and refresh the tool metadata and docs.

Type of Change

• Bug fix

Testing

96 targeted tests pass, including cursor resumption, empty pages with a cursor, rate-limit errors, and saved-workflow migrations. Full lint, repository audits, block registry validation, and docs manifest checks pass.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing
• No new warnings introduced

The PR appears safe to merge; the single-page cursor contract is consistently implemented, migrated, documented, and tested.

Summary

• Performs exactly one conversations.list request per invocation.
• Returns nextCursor and hasMore so callers can request subsequent pages.
• Removes the retired maxPages input and constant pages output.
• Migrates saved Slack block settings to remove channelMaxPages.
• Updates tests, generated metadata, deployment configuration, and documentation to match the new contract.
