Ruben Fiszel d9d45cf2f9 fix: lower default indexer memory/batch settings to prevent OOM (#8347)
The windmill-indexer pod was crash-looping due to OOMKilled (exit 137)
with a 2Gi memory limit. Two concurrent tantivy IndexWriters each
allocating 300MB (600MB total), combined with large uncommitted batches
of 50K jobs, caused memory exhaustion during indexing.

- writer_memory_budget: 300MB → 150MB (2 writers = 300MB total)
- commit_job_max_batch_size: 50,000 → 10,000
- commit_log_max_batch_size: 10,000 → 5,000

These can still be overridden via env vars or global settings.
