tests: add functional tests for DB message persistence, rebalance groups

Add backend-agnostic functional tests for database message persistence. All tests work with both SQLite and flat-file backends. New tests in test_history.c: - message_db_history_on_reopen: basic incoming write+read round-trip - message_db_history_multiple: 3 messages from different resources - message_db_history_contact_isolation: buddy1 msg absent from buddy2 - message_db_history_special_chars: XML entities survive decode+DB - message_db_history_outgoing: sent message persists across reopen - message_db_history_dialog: outgoing + incoming both in history - message_db_history_empty: no crash on contact with no history - message_db_history_long_message: 1000+ char body not truncated - message_db_history_newline: embedded LF stored correctly - message_db_history_service_chars: backslash pipe percent braces etc - message_db_history_verify: /history verify (ifdef HAVE_HISTORY_VERIFY) - message_db_history_lmc: XEP-0308 correction replaces original in DB Rebalance test groups for parallel execution (19/22/22/21): - Group 1: Connect, Ping, Rooms, Software, LastActivity - Group 2: Message, Receipts, Roster, DB History - Group 3: Chat Session, Presence, Disconnect - Group 4: MUC, Carbons
