Update style: Restaurant show page

[fnyxart]

Menu Container

• [x] Fix the price tag position to be in the right end & up - the corner of the dish card
• [x] Conditional show of "Allergens: none" (instead of "Alergens: ") if no allergens found (copy from Louisa's code on dish index - dish cards
• [x] Conditional show of "menu under review" when no dishes available at the restaurant

Map Container

• [x] Height of the container - not dependant on the height of the menu container (might need a TA | for difference look at restaurants that have dishes and those that don't - the map container should always display how it is when no dishes are shown (more compact))

@MarieW97, just a heads up, I fixed the height issue in the map container.
