improve memory leak detection tests with diagnostics and parallel support

- Rename test_linear_memory_growth.py to test_router_acompletion_memory_growth.py for clarity
- Add new test_proxy_chat_completions_memory_growth.py to test full proxy server memory usage
- Implement dynamic port allocation (18888-18919) in mock_server fixture for parallel test execution
- Add httpx client diagnostics to differentiate test artifacts from actual proxy memory growth
- Increase MEMORY_LIMIT to 170 MB based on empirical testing showing ~174 MB stable usage at scale
- Add aggressive cleanup routines with detailed logging to ensure accurate memory measurements
- Fix Windows Unicode compatibility by removing emoji characters from test output
- Tests now properly detect slow memory accumulation (~170 KB per 1000 requests) in proxy server

+Memory Leak Detection Tests - Proxy Server Linear Memory Growth
+
+Tests that check for linear/progressive memory growth in the proxy server by running 
+different numbers of requests (1k, 2k, 4k, 10k, 30k) with the same memory limit.
+
+These tests start an actual proxy server (not just the Router) and make HTTP requests
+to it, simulating real-world usage more accurately.
+
+IMPORTANT: These tests should be run INDIVIDUALLY, not all together. Running them
+together causes memory baseline drift between tests, making it difficult to detect
+linear growth accurately. Each test should be run in isolation:
+
+    pytest tests/load_tests/test_proxy_chat_completions_memory_growth.py::test_proxy_memory_baseline_1k -v
+    pytest tests/load_tests/test_proxy_chat_completions_memory_growth.py::test_proxy_memory_baseline_2k -v
+    # etc.
