feat: add switch stack port config with dynamic serial resolution

Browse Source 
- Add data source meraki_switch_stacks to resolve member serials by stack name
- Add switch_stack_port_configs variable: specify stack_name + port_range
  instead of individual switch serials
- Terraform applies port_range to ALL members of the stack automatically
- Merge switch_port_configs and switch_stack_port_configs into all_ports local
- Add example for bcn01-lab-stack01 (2x48p) in switch.auto.tfvars
