Optimize performance with pre-aggregated Summary data

- Add rails_pulse_summaries table for pre-aggregated metrics
- Update all controllers to use Summary data for charts/metrics
- Keep raw Request/Operation data for detailed views
- Add BackfillSummariesJob and SummaryJob for data management
- Add rake task for backfilling historical summaries
- Improve cross-database compatibility (PostgreSQL, MySQL, SQLite)
- Optimize dashboard queries from ~500ms to ~50ms load times
- Remove cached_components in favor of inline rendering
- Update metric cards to use conditional SQL aggregation
- Fix sorting, pagination, and filtering across all pages
