feat: full-stack Docker Compose integration tests

- 4-container stack: ClickHouse, platform (Rocky 9), bot-detector, dashboard
- Platform builds sentinel on Rocky (CGO+libpcap native), correlator static
- mod-reqin-log compiled with apxs on Rocky (matching RPM build target)
- ClickHouse init script patches credentials for test env (sed-based)
- 8-phase test runner: schema, traffic gen, pipeline, dashboard API, bot-detector, sentinel
- All 13 checks pass, 3 non-blocking warnings (empty dicts, log paths)

SQL schema fixes discovered during integration:
- 02_dictionaries: IPv6CIDR → String (not a valid ClickHouse type)
- 03_anubis_tables: dict_anubis_ua missing has_ip/rule_id/category attrs
- 03_anubis_tables: dict_anubis_country FLAT() → COMPLEX_KEY_HASHED() (String key)
- 09_audit_table: CODEC before DEFAULT → DEFAULT before CODEC
