Add sproc command for stored procedures

[mkrueger]

Summary

Adds a sproc command for working with Azure Cosmos DB stored procedures from the shell, with an interactive editor workflow and clean, human-friendly output.

Changes

• New sproc command with subcommands: list, show, create, exec, edit, delete (MCP-restricted).
• sproc list renders a human-readable table (Id / Last Modified / Size) for interactive sessions while still returning structured JSON for MCP consumers.
• sproc create opens an external editor, then shows a preview and a confirmation prompt before creating the stored procedure.
• sproc edit edits an existing stored procedure body and fails with a not-found error if it does not exist (use create to add a new one).
• Quick-exit editor handling: if the editor returns immediately, the shell waits for the user to finish editing and press Enter.
• Status messages (create/replace/delete/edit) now set IsPrinted so the JSON echo is hidden in the interactive shell and only surfaced over MCP.
• Removed the redundant --editor option from the theme and sproc commands.

Validation

• dotnet build CosmosDBShell.Tests/CosmosDBShell.Tests.csproj — succeeds.
• Sproc, localization audit, and help verification tests pass (32 passed / 0 failed).

CosmosDBShell/Azure.Data.Cosmos.Shell.Commands/ThemeCommand.cs:660

• ThemeCommand no longer supports --editor, but when no editor is found it still uses the theme-specific message key whose text says "or pass --editor=". This produces an incorrect user-facing error now that the option is removed.

        var editor = ExternalEditor.Resolve(null);
        if (editor is null)
        {
            var message = MessageService.GetString("command-theme-edit-no-editor");
            AnsiConsole.MarkupLine(Theme.FormatError(message));
            return new ErrorCommandState(new CommandException("theme", message));
