fix: report auth errors instead of silently proceeding unauthenticated

[anshul-garg27]

Summary

• Six helper commands silently swallowed authentication failures and proceeded with AuthMethod::None, causing confusing 401 API errors downstream
• Now they return a clear GwsError::Auth message with the underlying error
• --dry-run mode still works without auth (consistent with gmail helper pattern)

Affected helpers

Helper	File	Command
Chat	src/helpers/chat.rs	+send
Drive	src/helpers/drive.rs	+upload
Sheets	src/helpers/sheets.rs	+append, +read
Docs	src/helpers/docs.rs	+write
Calendar	src/helpers/calendar.rs	+insert
Script	src/helpers/script.rs	+push

Root cause

These helpers used a silent fallback pattern:

Err(_) => (None, executor::AuthMethod::None),

The gmail helper already uses the correct pattern:

Err(_) if matches.get_flag("dry-run") => (None, executor::AuthMethod::None),
Err(e) => return Err(GwsError::Auth(format!("... auth failed: {e}"))),

Test plan

• Verified all 7 call sites across 6 files are updated
• --dry-run exception preserved for all helpers
• Existing tests continue to pass

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly improves the user experience by enhancing error reporting for authentication failures across several helper commands. Instead of silently proceeding unauthenticated and leading to obscure API errors, these commands now provide clear and actionable GwsError::Auth messages, making it easier for users to diagnose and resolve authentication issues.

Highlights

• Authentication Error Handling: Six helper commands (Chat, Drive, Sheets, Docs, Calendar, Script) were updated to explicitly report authentication failures with a GwsError::Auth message, preventing silent unauthenticated execution and subsequent confusing 401 API errors.
• Dry-Run Exception Preserved: The --dry-run flag continues to allow unauthenticated operation for all affected helpers, maintaining consistency with the existing gmail helper pattern.

Code Review

This pull request fixes an issue where authentication failures were silently ignored in several helper commands by making them report auth errors. This change improves user experience by providing clear feedback. The implementation also correctly preserves existing --dry-run functionality. My review includes one suggestion to improve maintainability by refactoring the new, duplicated error handling logic into a shared function.
