server.address from span data silently overwritten by event server_name

When span.data already contains a server.address attribute (e.g. set by the WSGI integration from SERVER_NAME), this unconditional assignment overwrites it with the event-level server_name (the machine hostname), losing the more specific per-request value.

Evidence

• attributes.update(span_data) at line 207 merges all span data into attributes, which may include a server.address key (e.g. wsgi.py:402 sets attributes["server.address"] = server_name from environ["SERVER_NAME"]).
• The new code at line 228-229 then unconditionally does attributes["server.address"] = event["server_name"], overwriting the span-level value with the machine hostname.
• OTel semantic convention server.address refers to the logical server address the client is connecting to (not the machine hostname), so the overwrite introduces semantically incorrect data.
• The fix is to only set the fallback when server.address is not already present: if "server_name" in event and "server.address" not in attributes:.

Fix attempt detected (commit ed3fc20)

The commit added the exact line at issue (attributes['server.address'] = event['server_name']) unconditionally without the suggested and 'server.address' not in attributes guard, so the overwrite issue persists.

The original issue appears unresolved. Please review and try again.
