docs: add sql/init.sql + update README ClickHouse schema
- feat: sql/init.sql — initialisation complète ClickHouse (db, tables, MV, users) - feat: table http_logs mise à jour avec tous les champs réels du JSON corrélé - ajout tcp_meta_mss (UInt16), tcp_meta_window_scale (UInt8), tls_alpn (LowCardinality) - ajout keepalives, a_timestamp, b_timestamp, conn_id, ip_meta_id, ip_meta_total_length - ajout tous les header_* manquants (x_request_id, x_trace_id, sec_fetch_*, etc.) - correction types: ip_meta_id/ip_meta_total_length UInt32 → UInt16 - feat: vue matérialisée complète avec coalesce() sur tous les champs - docs: README schema section remplacée par référence à sql/init.sql + tableau des colonnes Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

### Architecture des tables
|
||||
|
||||
```
|
||||
http_logs_raw ← inserts du service (raw_json String)
|
||||
│
|
||||
└─ mv_http_logs ← vue matérialisée (parse JSON → colonnes typées)
|
||||
│
|
||||
▼
|
||||
http_logs ← table requêtable par les analystes
|
||||
```
|
||||
|
||||
### Table `http_logs` — colonnes
|
||||
|
||||
| Groupe | Colonnes |
|
||||
|---|---|
|
||||
| Temporel | `time` DateTime, `log_date` Date |
|
||||
| Réseau | `src_ip` IPv4, `src_port` UInt16, `dst_ip` IPv4, `dst_port` UInt16 |
|
||||
| HTTP | `method`, `scheme`, `host`, `path`, `query`, `http_version` (LowCardinality) |
|
||||
| Corrélation | `orphan_side`, `correlated` UInt8, `keepalives` UInt16, `a_timestamp`/`b_timestamp` UInt64, `conn_id` |
|
||||
| IP meta | `ip_meta_df` UInt8, `ip_meta_id` UInt16, `ip_meta_total_length` UInt16, `ip_meta_ttl` UInt8 |
|
||||
| TCP meta | `tcp_meta_options`, `tcp_meta_window_size` UInt32, `tcp_meta_mss` UInt16, `tcp_meta_window_scale` UInt8, `syn_to_clienthello_ms` Int32 |
|
||||
| TLS / fingerprint | `tls_version`, `tls_sni`, `tls_alpn` (LowCardinality), `ja3`, `ja3_hash`, `ja4` |
|
||||
| En-têtes HTTP | `header_user_agent`, `header_accept`, `header_accept_encoding`, `header_accept_language`, `header_x_request_id`, `header_x_trace_id`, `header_x_forwarded_for`, `header_sec_ch_ua*`, `header_sec_fetch_*` |

|

- **`No such column`** : vérifier que la table utilise la colonne unique `raw_json` (pas de colonnes séparées)

### Vue matérialisée vide
|

SHOW CREATE TABLE mv_http_logs;
|
||||
GRANT SELECT(raw_json) ON mabase_prod.http_logs_raw TO data_writer;
|

SHOW CREATE TABLE mabase_prod.mv_http_logs;
