* fix(uploads): fall back to configurable.thread_id when runtime.context lacks thread_id

runtime.context does not always carry thread_id depending on the
LangGraph invocation path. When absent, uploads_dir resolved to None
and the entire outline/historical-files attachment was silently skipped.

Apply the same fallback pattern already used by ThreadDataMiddleware:
try get_config().configurable.thread_id, with a RuntimeError guard for
test environments where get_config() is called outside a runnable context.

Discovered via live integration testing (curl against local LangGraph).
Unit tests inject uploads_dir directly and would not catch this.

* style: apply ruff format to uploads_middleware.py
