feat: replace MCP attachment tool with proxy endpoint
The MCP tool approach was impractical because it required the LLM to
generate large base64 strings token-by-token, causing timeouts.

Changes:
- Remove upload_attachment MCP tool
- Add POST /api/v1/attachments endpoint for multipart/form-data uploads
- Update proxy documentation to show both endpoints
- Uses existing GristClient.upload_attachment() method
- Requires write permission in session token
