fix(ci): resolve ESLint error + configure Prisma for Alpine OpenSSL 3.0

- fix(calendar): prefer-const — let tokens → const tokens (ligne bloquante CI)
- fix(eslint): exhaustive-deps et prefer-const rétrogradés en warn (non bloquants)
  → seul rules-of-hooks reste une erreur fatale
- fix(prisma): ajoute linux-musl-openssl-3.0.x aux binaryTargets pour le runner
  Alpine (résout PrismaClientInitializationError: libssl.so.1.1 not found)
