fix(roles): restringe usuarios Taller y Mecanico a solo la seccion de Taller y oculta precios

- sidebar.js: itemAllowed incluye mechanic junto a workshop -> solo muestra Taller
- app-init.js: redirige a /pos/workshop si el rol es workshop/mechanic
- config_bp.py: remueve customers.view y fleet.view de los permisos por defecto de workshop/mechanic
- workshop.js: hidePrices ahora tambien aplica para mechanic; oculta columnas/inputs de precio
- app-init.js/config.js: agrega etiquetas de rol para workshop y mechanic
- workshop.html: marca columnas de precio con price-col y oculta input catRate

Tests: 35 passed
