fix: correction bugs + tests + migration el7 vers el10

Correctifs de bugs critiques:
- Overflow entier dans le calcul du timestamp (nanoseconds)
- Validation des composantes temporelles dans format_iso8601
- Race condition mutex: échec dur pour MPM threadés (worker/event)
- Rejet des espaces en tête dans parse_int_strict

Nouveaux tests unitaires (38 ajoutés):
- Overflow timestamp, limites ISO8601, format fixe 20 chars
- Limite de taille JSON 64KB
- Détection headers sensibles (blacklist)
- Validation parse_int_strict
- dynbuf NULL handling et strlen mode

Migration packaging:
- Suppression CentOS 7 (EOL)
- Ajout AlmaLinux 10 (el10)
- RPMs supportés: el8, el9, el10

Mise à jour CI/CD et documentation:
- .gitlab-ci.yml: jobs verify pour el8/el9/el10
- architecture.yml: OS supportés à jour
- 70/70 tests pass
