* fix: batch-limit stale managed object cleanup to prevent 300K row UPDATE (#25257)

* Add STALE_OBJECT_CLEANUP_BATCH_SIZE constant

Configurable batch limit (default 1000) for stale managed object cleanup,
preventing unbounded UPDATE queries from hitting 300K+ rows at once.

* Batch-limit stale managed object cleanup with single bounded SQL query

Two fixes to _cleanup_stale_managed_objects:

1. Replace unbounded update_many with a single execute_raw using a
   subquery LIMIT, capping each poll cycle to STALE_OBJECT_CLEANUP_BATCH_SIZE
   rows. Zero rows loaded into Python memory — everything stays in Postgres.
   Uses the same PostgreSQL raw-SQL pattern as spend_log_cleanup.py
   (the proxy requires PostgreSQL per schema.prisma).

2. Extract _expire_stale_rows as a separate method for testability.

Keeps the file_purpose='response' filter to avoid incorrectly expiring
long-running batch or fine-tune jobs that legitimately exceed the
staleness cutoff.

* docs: add STALE_OBJECT_CLEANUP_BATCH_SIZE to env vars reference

* test: remove deprecated embed-english-v2.0 cohere embedding tests

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
