Pull request overview

This PR refactors protocol session acceptance specs to remove duplicated console/test-harness boilerplate by introducing a shared RSpec context and updating multiple protocol acceptance specs to use it.

Changes:

• Added protocol_session_acceptance shared context containing console setup, test harness, and session/rhost test generation.
• Updated SSH/SMB/Postgres/MySQL/MSSQL/LDAP acceptance specs to include the shared context and invoke run_protocol_session_tests.
• Normalized some string literals and added # frozen_string_literal: true to several acceptance spec files.

Impact Analysis:

• Blast radius: medium; affects all protocol acceptance specs migrated to the shared context (SSH/SMB/Postgres/MySQL/MSSQL/LDAP) and any future specs that adopt it.
• Data and contract effects: none; test-only refactor, but changes how acceptance test groups and hooks are generated/executed.
• Rollback and test focus: easy rollback (revert to per-spec boilerplate); focus validation on spec load/execution (ensuring run_protocol_session_tests is callable) and Allure metadata/attachments generation across at least one protocol suite.
