fix(c): Remove duplicate code generation for UUID path parameters

The C generator was generating duplicate path parameter handling code
when a parameter had format: uuid. This occurred because UUID parameters
have both isString=true and isUuid=true flags set, causing both the
{{#isString}} and {{#isUuid}} template blocks to execute.

The duplicate {{#isUuid}} block has been removed since it generated
identical code to the {{#isString}} block. This makes UUID parameters
consistent with email parameters, which already work this way
(isEmail=true and isString=true, but only use the {{#isString}} block).

The generated code now compiles successfully without duplicate variable
declarations.
