feat: optimize hot database queries with multi-layer caching (#19068)

## Summary

Introduces multi-layer caching for the 5 most frequent database queries
identified in production (Sentry data), targeting the JWT authentication
hot path and cron job logic.

### Problem
Our database is under heavy load from uncached queries on the auth hot
path:
- `WorkspaceEntity` lookups: **638 queries/min**
- `ApiKeyEntity` lookups: **491 queries/min**
- `UserEntity` lookups: **147 queries/min**
- `UserWorkspaceEntity` lookups: **143 queries/min**
- `LogicFunctionEntity` lookups: **1800 queries/min** (cron job)

### Solution

**1. New `CoreEntityCacheService`** for non-workspace-scoped entities
(Workspace, User, UserWorkspace):
- Mirrors `WorkspaceCacheService` architecture (in-process Map + Redis
with hash validation)
- Provider pattern with `@CoreEntityCache` decorator
- Keyed by entity primary key (not workspaceId)
- 100ms local TTL, Redis-backed hash validation for cross-instance
consistency
- Three providers: `WorkspaceEntityCacheProviderService`,
`UserEntityCacheProviderService`,
`UserWorkspaceEntityCacheProviderService`

**2. New `apiKeyMap` WorkspaceCache** for workspace-scoped API key
lookups:
- `WorkspaceApiKeyMapCacheService` loads all API keys for a workspace
into a map by ID
- Leverages existing `WorkspaceCacheService` infrastructure
- Cache invalidation on API key create/update/revoke

**3. `CronTriggerCronJob` refactored** to use existing
`flatLogicFunctionMaps` workspace cache:
- Eliminates per-workspace `LogicFunctionEntity` repository queries
(~1800/min)
- Filters cached data in-memory instead

**4. `JwtAuthStrategy` refactored** to use caches for all entity
lookups:
- Workspace, User, UserWorkspace → `CoreEntityCacheService`
- ApiKey → `WorkspaceCacheService` (`apiKeyMap`)
- Impersonation queries kept as direct DB queries (rare path, requires
relations)

**5. Cache invalidation** wired into mutation paths:
- `WorkspaceService` → invalidates `workspaceEntity` on
save/update/delete
- `ApiKeyService` → invalidates `apiKeyMap` on create/update/revoke

### Architecture

```
Request → JwtAuthStrategy
  ├── Workspace lookup → CoreEntityCacheService (in-process → Redis → DB)
  ├── User lookup → CoreEntityCacheService (in-process → Redis → DB)
  ├── UserWorkspace lookup → CoreEntityCacheService (in-process → Redis → DB)
  └── ApiKey lookup → WorkspaceCacheService (in-process → Redis → DB)

CronTriggerCronJob
  └── LogicFunction lookup → WorkspaceCacheService (flatLogicFunctionMaps)
```

### Expected Impact
| Query | Before | After |
|-------|--------|-------|
| WorkspaceEntity | 638/min | ~0 (cached) |
| ApiKeyEntity | 491/min | ~0 (cached) |
| UserEntity | 147/min | ~0 (cached) |
| UserWorkspaceEntity | 143/min | ~0 (cached) |
| LogicFunctionEntity | 1800/min | ~0 (cached) |

### Not included (ongoing separately)
- DataSourceEntity query optimization (IS_DATASOURCE_MIGRATED migration)
- ObjectMetadataEntity query optimization (already partially cached)
