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

+### Security checks
+
+We have a static analyzer `check-cwe134.sh` that detects CWE-134 format string vulnerabilities. It runs automatically in CI but you can also run it locally:
+
+```bash
+./check-cwe134.sh
+```
+
+This checks for unsafe patterns where data could be passed directly as a format string to functions like `printf`, `cons_show`, etc. Never pass a raw string for formatting; use `"%s"` format specifier instead.
+
 ### Finding typos
 
 We include a `.codespellrc` configuration file for `codespell` in the root directory.
