[aidanharan]

Upgrade the adapter so that it passes against Rails main branch till after rails/rails#55897 was merged.

[Copilot]

Pull request overview

This PR upgrades the ActiveRecord SQL Server adapter to be compatible with Rails main branch after the introduction of the QueryIntent parameter object pattern (Rails PR #55897). The changes refactor the adapter to use the new QueryIntent API instead of passing individual sql, binds, and name parameters.

Changes:

• Refactored database statement methods to use QueryIntent parameter object pattern
• Updated test assertions to match new Rails error message formats
• Fixed query cache to use accessor method instead of instance variable
• Enhanced timestamp logic to respect user-provided values in upsert operations
