feat(spec,crm-example): translate sidebar group labels via navigation convention

Adds an optional navigation field to the apps.<name> entry in
TranslationData so each translation pack can localise sidebar
navigation group labels following the new objectui
{ns}.apps.{appName}.navigation.{groupId}.label convention.

- packages/spec: TranslationDataSchema.apps[name] now accepts an
  optional navigation record of { label } entries.
- examples/app-crm: en/zh-CN/es-ES/ja-JP translations gain
  apps.crm_enterprise.navigation entries for the five CRM sidebar
  groups (group_sales, group_service, group_marketing, group_products,
  group_analytics). The crm.app.ts metadata keeps English literals
  as the in-source fallback.

Tests: @objectstack/spec suite passes (6811 tests).
