Remove duplicated socket and TLS log identity prefixes

[VolkerChristian]

Motivation

• Remove duplicated connection-name or instance-name free-text prefixes from proven object-scoped socket/TLS logger messages identified by the authoritative audit to avoid redundant human-readable output while preserving structured metadata.
• Preserve logger surface, log levels, control flow, TLS/error behavior and do not change ssl_log() or other static/helper logging patterns.

Description

• Edited 5 files to remove duplicated formatting placeholders and arguments from 23 audited call sites and to drop 4 lambda captures that became unused as a direct mechanical consequence of those removals: src/core/socket/stream/SocketClient.h, src/core/socket/stream/SocketServer.h, src/core/socket/stream/tls/SocketConnection.hpp, src/core/socket/stream/tls/SocketAcceptor.hpp, and src/core/socket/stream/tls/SocketConnector.hpp.
• Audit group mapping implemented: CSI-P044, CSI-P048: SocketClient/SocketServer instance prefixes; CSI-P049–CSI-P055: TLS SocketConnection prefixes; CSI-P056, CSI-P058, CSI-P060, CSI-P061: TLS accept-side handshake callback prefixes; CSI-P066, CSI-P068, CSI-P070, CSI-P071: TLS connect-side handshake callback prefixes; CSI-P062–CSI-P064, CSI-P072–CSI-P074: TLS endpoint configuration instance prefixes.
• Removed only the duplicated getInstanceName() / getConnectionName() placeholders and their function arguments/stream prefixes, preserved ssl_log() calls and SNI/config callback logging, and ensured resulting free-text messages start cleanly (e.g. with SSL/TLS: where applicable).
• Per the audit rules, no logger surface, formatting, backend, category, level, helper, or architectural logging changes were made.

Testing

• Built a debug test configuration and compiled the smallest set of targets that exercise the modified files; built targets included core-socket-stream, core-socket-stream-legacy, core-socket-stream-tls, net-in-stream-legacy, net-in-stream-tls, net-in6-stream-legacy, net-in6-stream-tls, net-un-stream-legacy, and net-un-stream-tls, and the relevant semantic migration and socket/TLS test executables; builds completed successfully.
• Enabled tests and ran selected unit/migration tests (SemanticLoggerRound2Test, SocketEndpointLogApiRound5Test, SocketConnectionMigration01Test, SocketConnectorAcceptorMigration02Test, SocketServerClientMigration03Test, TlsSocketStreamMigration06Test and related composition tests); the selected tests passed and composition tests were skipped by existing runtime conditions.
• Ran repository checks and formatting: git diff --check showed no whitespace problems and clang-format -i was applied to all modified C++ files.
• Performed search/manual verification with rg over the five scoped files for getConnectionName|getInstanceName|connectionName and for the SSL/TLS logging patterns and inspected remaining results to ensure only expected identity use remains (e.g., ssl_log(), OpenSSL ex-data, SNI/config callbacks, another-object logging and scope construction).

Notes: 23 audited logging call sites inspected, 23 message prefixes removed, 4 lambda captures removed because they became unused; structured inst= and conn= metadata remain unchanged; ssl_log() and KEEP/other excluded rows were left intact.
