Accept raw payload on convert-endpoint and respond with raw Yjs payload
This change replaces Base64-encoded I/O with direct binary streaming,
yielding several benefits:
- **Network efficiency**: Eliminates the ~33% size inflation of Base64,
cutting bandwidth and latency.
- **Memory savings**: Enables piping DOCX (already compressed) buffers
straight to DocSpec API without holding, encoding and decoding multi-MB
payload in RAM.

Renamed the `convert-markdown` endpoint to `convert` as a
general-purpose conversion endpoint for integration with DocSpec
conversion (DOCX import), without altering its existing functionality.
In a future contribution, this endpoint will not only support conversion
from Markdown -> BlockNote -> Yjs but also directly BlockNote -> Yjs.
