fix(test): handle integer values in mock getBoolParam

The mock's getBoolParam only handled bool and string types. When the
client sends start=1 as a JSON integer it decodes as float64, falling
through to the default branch and returning false. Add float64 and int
cases so numeric 1/0 values correctly map to true/false.
