refactor: remove webmail interface, focus on core mail storage functionality

- Remove obsolete CouchDB design documents (webmail.json, dashboard.json)
- Clean up webmail-related code from couch/couch.go (WebmailViews, CreateWebmailViews, etc.)
- Update documentation to focus on core mail-to-CouchDB storage functionality
- Add Future Plans section describing planned webmail viewer as separate component
- Apply go fmt formatting and ensure code quality standards
- Update test documentation to show raw CouchDB API access patterns
- Remove compiled binary from repository

This refactor simplifies the codebase to focus on its core purpose: efficiently
backing up emails from IMAP to CouchDB. The webmail interface will be developed
as a separate, optional component to maintain clean separation of concerns.

### Accessing Stored Emails
Once mail2couch has synced your emails, you can access them through CouchDB's REST API:
#### Raw Data Access
```bash
# List all databases
http://localhost:5984/_all_dbs
# View database info
http://localhost:5984/{database}
# List all documents in database
http://localhost:5984/{database}/_all_docs
# Get individual message

# Get message with attachments

## Future Plans
### CouchDB-Hosted Webmail Viewer
We plan to develop a comprehensive webmail interface for viewing the archived emails directly through CouchDB. This will include:
- **📧 Modern Web Interface**: A responsive, Gmail-style webmail viewer built on CouchDB design documents
- **🔍 Advanced Search**: Full-text search across subjects, senders, and message content
- **📁 Folder Organization**: Browse messages by mailbox with visual indicators and statistics
- **📎 Attachment Viewer**: Direct download and preview of email attachments
- **📱 Mobile Support**: Optimized interface for tablets and smartphones
- **🎨 Customizable Themes**: Multiple UI themes and layout options
- **⚡ Real-time Updates**: Live synchronization as new emails are archived
- **🔐 Authentication**: Secure access controls and user management
- **📊 Analytics Dashboard**: Email statistics and storage insights
This webmail viewer will be implemented as:
- **CouchDB Design Documents**: Views, shows, and list functions for data access
- **Self-contained HTML/CSS/JS**: No external dependencies or servers required
- **RESTful Architecture**: Clean API endpoints for integration with other tools
- **Progressive Enhancement**: Works with JavaScript disabled for basic functionality
The webmail interface will be a separate component that can be optionally installed alongside the core mail2couch storage functionality, maintaining the clean separation between data archival and presentation layers.
