* Python: Forward GitHub Copilot input attachments as inline blobs
The Python GitHubCopilotAgent built the prompt from message text only, so
DataContent (images/documents) passed on input was silently dropped. The .NET
provider already forwards these as attachments.
Map input data content to the Copilot SDK's inline BlobAttachment (base64,
no temp files) in both the streaming and non-streaming send paths. Data content
without a media type is dropped with a warning instead of silently.

* Python: Handle non-base64 data URIs and fix attachment docstring
Address PR review feedback:
- Guard _get_data_bytes_as_str against ContentError so a non-base64 data:
URI (which _validate_uri still classifies as type="data") is skipped with a
warning instead of failing the entire Copilot request.
- Correct the docstring: remote URIs and non-base64 data URIs are neither
attached nor added to the prompt (the prompt is built from text content only).
- Add tests for the non-base64 data URI path.

* Python: Fix flaky attachment test under telemetry
The end-to-end non-base64 data URI test failed in CI because GitHubCopilotAgent's
telemetry layer serializes message content (observability._to_otel_part ->
_get_data_bytes_as_str), which raises ContentError on a non-base64 data: URI
before the attachment code runs. That is an unrelated core-observability
limitation, not attachment behavior.
Use RawGitHubCopilotAgent (no telemetry layer) for that test so it isolates the
provider's send path. The direct helper test still covers the ContentError guard.
