Migrate cron, databaseEventTrigger, httpRoute triggers to serverless functions (#17488)

## Summary

Migrates trigger entities (`CronTriggerEntity`,
`DatabaseEventTriggerEntity`, `RouteTriggerEntity`) into
`ServerlessFunctionEntity` by storing trigger settings as JSONB columns
directly on the serverless function. This simplifies the architecture
since these relationships were effectively one-to-one.

## Changes

### Schema Changes
- Added three new nullable JSONB columns to `ServerlessFunctionEntity`:
  - `cronTriggerSettings` - stores cron pattern
- `databaseEventTriggerSettings` - stores event name and updated fields
filter
- `httpRouteTriggerSettings` - stores path, HTTP method, auth
requirements, and forwarded headers

### Core Logic Updates
- `CronTriggerCronJob` - now queries `ServerlessFunctionEntity` directly
instead of `CronTriggerEntity`
- `CallDatabaseEventTriggerJobsJob` - now queries
`ServerlessFunctionEntity` directly
- `RouteTriggerService` - now queries `ServerlessFunctionEntity`
directly
- `ApplicationSyncService` - extracts trigger settings from manifest and
writes to serverless function
