Paul Rastoin d640b93096 Improve v2 and cache invalidation perfs (#15467 )

# Introduction
Log are debug logs of
`packages/twenty-server/test/integration/metadata/suites/object-metadata/create-delete-and-create-object-metadata-v2.integration-spec.ts`run
ten times in a row on clean db reset

## Next
Will improve cache computation to lighter invalidation.
RelationLoad `query` does not seem to work with typeorm so I'll continue
the custom integration i've started in
https://github.com/twentyhq/twenty/tree/optimize-cache-read-v2

## Integration tests duration
Significant test duration improvement too

## What's next
- The legacy cache invalidation removal
- Factorizing redis calls in only one operation

## Autogenerated performance comparison ( including mutation refactor
too )

[After](https://gist.github.com/prastoin/7bfddd14bfded2e4991a9378970a026d)

The optimized implementation shows **dramatic performance improvements**
across all metrics:

- 🚀 **Cache Invalidation**: 156.3ms → 76.8ms (**50.9% faster**)
- 🚀 **Builder Operations**: 21.3ms → 14.2ms (**33.3% faster**)
- ⚡ **Consistency**: 16.4% more predictable performance
