P2 Badge Serialize concurrent dropped-count updates

When multiple application threads finish spans or start traces while the queue is full, both callbacks can read the same _dropped_count value before either stores its increment, causing the public metric to undercount dropped telemetry; this is especially reachable on free-threaded Python builds and other interpreters because += is not an atomic counter operation. Protect both increments and reads with a shared lock or another thread-safe counter, and cover the interleaving with a controlled concurrency test rather than only the sequential test.

P2 Badge Serialize concurrent dropped-count updates

When multiple application threads finish spans or start traces while the queue is full, both callbacks can read the same _dropped_count value before either stores its increment, causing the public metric to undercount dropped telemetry; this is especially reachable on free-threaded Python builds and other interpreters because += is not an atomic counter operation. Protect both increments and reads with a shared lock or another thread-safe counter, and cover the interleaving with a controlled concurrency test rather than only the sequential test.
