perf(env-filter): make envs cached again

[nimarb]

Important

Introduce caching for environment filter options to optimize data fetching in dashboard components.

• Caching:
  • Introduce useEnvironmentFilterOptionsCache in use-environment-filter-options-cache.tsx to cache environment filter options.
  • Cache entries are keyed by projectId and time range bucket, with TTLs based on time range duration.
  • Prunes expired cache entries and deduplicates options.
• Integration:
  • Replace direct API calls with useEnvironmentFilterOptionsCache in index.tsx of both dashboards/[dashboardId] and project/[projectId].
  • Use cached environment options for filter components and loading states.
• UI Changes:
  • Add NoDataOrLoading component to handle loading states in project/[projectId]/index.tsx.
