Clean: Remove all obsolete ETCP tests, keep only working handshake test

Deleted 13 obsolete ETCP and connection test files:
- test_etcp.c, test_etcp_2instance.c, test_etcp_connection_init.c
- test_etcp_connections_send.c, test_etcp_link_crypto_working.c
- test_etcp_link_simple.c, test_etcp_simple.c, test_etcp_stress.c
- test_etcp_connection_full.c, test_etcp_connection_real.c
- test_etcp_full_lifecycle.c, test_etcp_new.c, test_etcp_simple_real.c

Updated Makefile.am to include only:
- test_etcp_two_instances_fixed (working handshake test)
- Essential module tests (routing, secure_channel, lib, etc.)

Result: Clean test suite with only functional ETCP handshake demonstration
