fix(fonts): sincronizar @font-face en critical-bootstrap.css

El archivo critical-bootstrap.css (TIPO 2) carga primero y tenia
valores desactualizados que causaban el salto visual en navbar.

Cambios:
- font-display: optional → swap
- size-adjust: 106% → 100.6%

Ahora ambos archivos (@font-face) estan sincronizados:
- critical-bootstrap.css (inline P:0)
- css-global-fonts.css (deferred)
