toto 8ca4a1e849 feat(mod_reqin_log): fingerprinting HTTP/2 passif (Akamai format) 
Ajoute un filtre d'entrée de connexion (AP_FTYPE_CONNECTION, APR_HOOK_LAST)
qui s'insère entre mod_ssl et mod_http2 pour lire de manière non-destructive
le preface HTTP/2 (RFC 9113 §3.4) et en extraire :

- h2_fingerprint    : fingerprint Akamai complet
                      ex. '1:65536,2:0,4:6291456,6:262144|15663105|0|m,a,s,p'
- h2_settings_fp    : entrées SETTINGS brutes  (ex. '1:65536,4:6291456')
- h2_window_update  : incrément WINDOW_UPDATE  (ex. '15663105')
- h2_pseudo_order   : ordre des pseudo-headers (ex. 'm,a,s,p' Chrome,
                                                     'm,p,s,a' Firefox)

Technique : lecture spéculative AP_MODE_SPECULATIVE (non-destructive)
de 512 octets — la donnée reste disponible pour mod_http2. Le filtre
se retire de la chaîne après la première invocation.

Stockage dans c->notes (H2_NOTE_*) puis émission JSON dans log_request().
ClickHouse : 4 nouvelles colonnes dans http_logs + JSONExtract dans mv_http_logs.
Migration pour déploiements existants : 04_http2_fields.sql.
14 tests unitaires (cmocka) couvrent Chrome/Firefox/HTTP1/troncature/HPACK.
