perf(plugin-search): reduce query depth in hooks (#12225)

Perf improvements and reliability of document reindexing and
synchronization of plugin-search functions.

## What

Reindex Handler (generateReindexHandler.ts):
- Replaced `Promise.all` with sequential `await` to prevent transaction
issues.
- Added `depth: 0` to payload.find for lighter queries.

Sync Operations (syncDocAsSearchIndex.ts):
- Standardized depth: 0 across create, delete, update, and find API
calls.
- Streamlined conditionals for create operations.

## Why
Improved performance with reduced query overhead.
Enhanced transaction safety by avoiding parallel database operations.
