Serveur réécrit en Rust

Le serveur Dart (bin/) est remplacé par un serveur Rust (server/) :
tokio + axum, reqwest/rustls, SQLite embarqué via rusqlite. Même API,
mêmes routes et mêmes réponses : le front Flutter ne change pas.

La base de production est reprise telle quelle : schéma, migrations et
formats de dates (DateTime.toIso8601String de Dart) sont reproduits à
l'identique, les sessions et hachages existants restent valides.

Comportement conservé : cascade de routage, anti-SSRF, logs masqués,
rate limits, transcodage HLS/turbo.ts avec repli GPU, quotas fournisseur,
enregistrements (reprise, relances, fusion), season passes, EPG, logos de
repli, arrêt gracieux sur SIGTERM. Tests Dart portés (132 tests Rust) ;
la CI exécute fmt, test et clippy -D warnings, l'image Docker compile le
serveur dans un étage rust:1.98.1.
