Fix get_dynamic_mapped_parameter for nested map keys

The old implementation only returned the key names without the parent
struct path prefix. This caused generated code to reference non-existent
members like 'updated_params.entries' instead of 'updated_params.nested.entries'.

Changes:
- Rename old get_dynamic_mapped_parameter to get_dynamic_mapped_parameter_names
- Create new get_dynamic_mapped_parameter that builds full paths including
  parent struct prefixes (e.g., 'nested.entries' instead of just 'entries')
- Update get_dynamic_parameter_map to use the renamed function
