v1.2.7 - Fix Price Format (Pounds not Pence)

Fixed price format bug where prices were incorrectly treated as pence instead of pounds.

Changes:

• MCP get_drinks: Fixed price_gbp formatting and added price_pounds field
• MCP get_menu_details: Fixed food price formatting
• Fixed Drink model comment: Price is in pounds (e.g., 1.62 = £1.62)

Before (wrong):

• price_pence: 1.62 (actually pounds!)
• price_gbp: £0.02 (dividing pounds by 100)

After (correct):

• price_pounds: 1.62
• price_pence: 162
• price_gbp: £1.62
