refactor: rename plugin from MokoWaaSBrand to MokoWaaS

Drop the "Brand" suffix from all naming conventions:
- PascalCase: MokoWaaSBrand → MokoWaaS
- lowercase: mokowaasbrand → mokowaas
- Display: MokoWaaS-Brand → MokoWaaS
- Language keys: PLG_SYSTEM_MOKOWAASBRAND → PLG_SYSTEM_MOKOWAAS

Renames 6 files and updates 28 files across PHP, XML, INI,
Markdown, YAML, and shell scripts.
