Calendar Integration: Propose Calendar Items for Time Logging

[Copilot]

This PR implements comprehensive calendar integration for TimeHarbor, enabling users to connect their external calendars (Google Calendar and Microsoft Outlook) and automatically suggest time entries based on their scheduled meetings and appointments.

Overview

The calendar integration provides a privacy-first approach to time tracking suggestions, where users can connect their calendars via OAuth 2.0 and review upcoming/recent events for potential time logging. The system never automatically logs time entries - all suggestions require explicit user confirmation.

Key Features Implemented

Calendar Connection & OAuth

• Secure OAuth 2.0 integration for Google Calendar and Microsoft Outlook
• Visual connection status dashboard with last sync timestamps
• One-click connect/disconnect functionality with proper error handling
• Encrypted token storage with automatic refresh capabilities

Event Management & Suggestions

• Automatic fetching of calendar events (past 7 days + next 7 days)
• Smart filtering to exclude all-day events, cancelled meetings, and very short appointments
• Intelligent project matching based on event titles and existing TimeHarbor projects
• Duration calculation with user-adjustable time suggestions

User-Controlled Workflow

• Events presented in a clean review interface with event details
• Users can confirm, adjust time, dismiss, or snooze events
• No automatic time logging - every entry requires explicit user confirmation
• Time adjustment controls allow users to modify suggested durations before logging

Real-time Integration

• Webhook endpoints for Google Calendar push notifications and Microsoft Graph subscriptions
• OAuth callback handlers for seamless authentication flow
• Live calendar event refreshing with proper error handling
• Background synchronization without blocking the user interface

Technical Implementation

Database Schema

• New CalendarConnections collection for storing encrypted OAuth tokens
• New CalendarEvents collection for temporary event caching and status tracking
• Proper indexing and user-scoped data access

Server-Side Methods

• calendar.initiateOAuth() - Generate OAuth authorization URLs
• calendar.refreshEvents() - Fetch events from calendar APIs
• calendar.confirmEvent() - Convert calendar events to time entries
• calendar.disconnect() - Remove calendar connections securely

Client-Side Features

• Reactive UI components using Meteor's Blaze templates
• Real-time updates when calendar data changes
• Mobile-responsive design consistent with TimeHarbor's existing UI
• Home page notifications when calendar events need review

Security & Privacy

• Read-only calendar access with minimal required permissions
• No permanent storage of detailed calendar event data
• User consent required for all time entry creation
• Comprehensive privacy documentation and user controls

Documentation

Added comprehensive documentation in calendar.md covering:

• Supported calendar providers and required OAuth setup
• Privacy practices and data handling policies
• Technical implementation details and troubleshooting
• Configuration examples and environment setup

Testing

Implemented test suite covering:

• Calendar connection creation and management
• Event creation, confirmation, and dismissal workflows
• Database operations and data validation
• Error handling and edge cases

This implementation enhances TimeHarbor's time tracking capabilities while maintaining the application's core principle of user-controlled, privacy-first time management.

Fixes #43.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• install.meteor.com
  • Triggering command: curl REDACTED (dns block)

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)

Fixed the templating syntax error in commit 6601bf1. The issue was caused by nested {{#if}} blocks inside HTML attributes, which isn't allowed in Meteor's Spacebars templating engine. I replaced the nested conditionals with a proper helper function isSelectedTeam() that returns the selected attribute value when appropriate.

Could you clarify what specific content was deleted? I see that the README.md feature list was renumbered when I added the calendar integration feature, but the content appears to have been preserved - just shifted down by one number. If there's something specific that was removed that shouldn't have been, please point it out and I'll restore it.
