etcp: replace connections linked-list with indexed ll_queue, add state/ref_count lifecycle
...
- Remove ETCP_CONN.next linked-list, UTUN_INSTANCE.connections list/count
- Unified connections in single ll_queue indexed by peer_node_id (0=pending)
- struct conn_queue_entry { peer_node_id, conn* } for uniform queue data
- Connection lifecycle via etcp.c: create→pending, conn_ready→indexed, close→detach+deferred free
- Close split: phase1 detach from external world, phase2 deferred via uasync_call_soon
- etcp_conn_set_peer_node_id: reindex on ID change (WARN)
- etcp_conn_ref_take/free: blocking close until refcount returns to 0
- Remove chat_connections — use unified connections queue directly
- Update all iteration/search patterns across 40 files (src + tests + chatgui)

crypto: migrate ECDH(secp256r1) to X25519, drop TinyCrypt
...
- SC_PUBKEY_SIZE: 64 -> 32 bytes, SC_PUBKEY_ENC_SIZE: 72 -> 40
- sc_set_peer_public_key uses EVP_PKEY_derive with X25519
- sc_generate_keypair via EVP_PKEY_keygen(EVP_PKEY_X25519)
- sc_compute_public_key_from_private via EVP_PKEY_new_raw_private_key
- sc_validate_key: check non-zero (X25519 has no invalid keys)
- sc_obfuscate_pubkey: XOR now 32 bytes
- Remove all TinyCrypt code (~860 lines), always use OpenSSL
- Remove TinyCrypt from build system, drop test_crypto/test_ecc_encrypt
- Update all test keys (128 hex -> 64 hex)
- Fix bbr_integration.c split-line pubkeys

Config: Added [allowed_keys] section for client public key authorization on server
...
- Added CFG_ALLOWED_KEY struct with binary key storage (64 bytes) for fast memcmp comparison
- Implemented parsing of [allowed_keys] section with allow_all flag and per-key entries
- Added key validation in etcp_connections.c server handler (errorcode=8 for rejected keys)
- Default behavior: deny all if [allowed_keys] section is missing or allow_all=0 with no keys
- Added proper memory cleanup and debug logging for allowed_keys configuration
- Updated all test configs to include [allowed_keys] allow_all=1 for backward compatibility
