enhancement: Add TAKConfig message for on-device TAK team/role configuration

Add TAKConfig to ModuleConfig with Team and MemberRole fields,
allowing TAK_TRACKER devices to configure ATAK group settings
instead of using hardcoded defaults.

- module_config.proto: TAKConfig message (team, role) at oneof field 16
- localonly.proto: tak field at position 17 in LocalModuleConfig
- admin.proto: TAK_CONFIG = 15 in ModuleConfigType enum
