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
