refactor: drop legacy metrics database schema

[Chaitu-Tatipamula]

Summary

Adds a database migration to drop the legacy metrics schema objects and removes the corresponding TypeORM entity files and module registrations. This completes step 9 of #275.

Depends on #441.

Changes

[NEW] Migration 1762000000000-DropMetricsSchema

Drops the following database objects in dependency order:

1. refresh_sp_performance_last_week() and refresh_sp_performance_all_time() functions
2. sp_performance_last_week and sp_performance_all_time materialized views
3. metrics_daily table (with CASCADE)
4. metrics_daily_metric_type_enum and metrics_daily_service_type_enum types

⚠️ This migration is irreversible. Restore from backup if rollback is needed.

Deleted entity files

• metrics-daily.entity.ts
• sp-performance-all-time.entity.ts
• sp-performance-last-week.entity.ts

Modified

• database.module.ts — Removed MetricsDaily, SpPerformanceAllTime, SpPerformanceLastWeek from entity registrations, forFeature, providers, and exports
• types.ts — Removed MetricType enum (only consumer was the deleted entity)

Verification

• pnpm typecheck ✅
• pnpm test ✅ (249 tests)
• pnpm check:ci ✅

Pull request overview

Removes the legacy “metrics” persistence layer by dropping the underlying Postgres objects and deleting the corresponding NestJS/TypeORM code and configuration that referenced them, completing step 9 of #275.

Changes:

• Added a TypeORM migration to drop legacy metrics functions, materialized views, table, and enum types.
• Removed legacy metrics module/services/controllers/DTOs/utils and TypeORM entities; unregistered them from the DB/app modules.
• Removed metrics-related pg-boss queues/scheduling/config (METRICS_PER_HOUR) and updated related docs/manifests.

Could you update the e2e migration tests to include the new migration DropMetricsSchema1762000000000?

Could you update the e2e migration tests to include the new migration DropMetricsSchema1762000000000?

so i was looking into this and there is a subtle issue with including DropMetricsSchema in the existing e2e roundtrip test.
the problem is DropMetricsSchema is irreversible. the existing roundtrip test undoes 7 migrations from the end to get back to before RemoveSpReceivedRetrieveRequest, then re-applies them. But several of those undone migrations (RemoveIpniRetrievedColumns, RemoveSpReceivedRetrieveRequest) have down() methods that ALTER TABLE metrics_daily, which no longer exists after DropMetricsSchema irreversibly drops it.
maybe we can use isolated databases or at worst adding metrics_daily existence guards to every migration that references it wdyt?
