Fix PresignedUrlResponse model to match API response format (#125)

# Fix PresignedUrlResponse model to match API response format

## Summary

Fixes a Pydantic validation error when uploading videos using the vlmrun
Python client (v0.3.4). The issue was that the `PresignedUrlResponse`
model expected `method` and `expiration` fields, but the actual API
response returns `upload_method` and `public_url` instead.

**Changes:**
- Added `upload_method` and `public_url` fields that the API actually
returns
- Made `method` and `expiration` optional with default `None` since the
API doesn't return them
- Preserved all existing fields used by the upload logic (`id`, `url`,
`filename`, `content_type`, `created_at`)

## Review & Testing Checklist for Human

- [ ] **Test video upload end-to-end** - Verify that uploading videos
with presigned URLs now works without Pydantic validation errors
- [ ] **Check for field dependencies** - Search codebase to ensure no
other code relies on `method` or `expiration` fields being non-None
- [ ] **Verify API response format** - Confirm the actual API response
matches the updated model by testing or reviewing API documentation

### Notes

- Tests pass (129 passed, 1 unrelated OpenAI test failure)
- Lint checks pass
- The upload logic in `files.py` only uses `response.id`,
`response.url`, and `response.content_type` which are all preserved
- Based on user report and direct API call showing actual response
format
