Further refine i18n structure

- Remove "nav" section, use "entities" references instead
- Remove composite strings like "Total Nodes", "Recent Advertisements"
  - Use composed patterns: t('common.total_entity', { entity: t('entities.nodes') })
  - Use common.recent_entity, common.edit_entity, common.add_entity patterns
- Hardcode MeshCore tagline (official trademark, not configurable)
- Update all page components and templates to use entity-based translations
- Update tests to reflect new structure
- Remove redundant page-specific composite keys

This maximizes reusability and reduces duplication across translations.
