Replace brittle path construction with repository root detection in PostgreSQL tests

[Copilot]

The PostgreSQL repository tests used multiple ".." operators to construct the path to schema.sql, making them fragile across different test execution environments.

Changes

• Added FindRepositoryRoot() helper: Searches upward for .git directory to reliably locate repository root
• Replaced hardcoded path traversal: Eliminated six ".." operators in favor of dynamic root detection
• Fixed XML documentation: Removed placeholder tags and corrected property descriptions

Implementation

private static string FindRepositoryRoot()
{
    var currentDirectory = new DirectoryInfo(Directory.GetCurrentDirectory());
    
    while (currentDirectory != null)
    {
        if (Directory.Exists(Path.Combine(currentDirectory.FullName, ".git")))
        {
            return currentDirectory.FullName;
        }
        currentDirectory = currentDirectory.Parent;
    }
    
    throw new DirectoryNotFoundException(
        "Could not find repository root. Ensure tests are run from within the repository.");
}

Path construction now uses Path.Combine(FindRepositoryRoot(), "database", "sql", "postgresql", "schema.sql") instead of relative navigation.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
