Dantuluri Surya Narayana Raju ee71d69db0 fix(router): use .get() for 'hidden' and 'model' keys in dict-style model_group_alias entries
RouterModelGroupAliasItem is a TypedDict with required fields 'model'
and 'hidden', but TypedDict is a type-hint only — Python does not
validate or inject keys at runtime.  Any user whose config omits the
'hidden' key (natural, since it is only needed to hide a group) gets a
plain dict without it:

    model_group_alias:
      'gpt-4-alias': {model: gpt-3.5-turbo}   # no hidden key

This caused a KeyError on every request because:
  - get_model_group_info() is called by set_response_headers on every
    router completion (confirmed by source comment)
  - get_model_list_from_model_alias() is called during Router.__init__
    via set_model_list -> get_model_names

Both call sites used item['hidden'] and item['model'] directly.

Fix: switch to item.get('hidden') and item.get('model', '') in both
locations.  item.get('hidden') returns None when the key is absent,
and None is not True, so the visibility logic is preserved correctly.

Adds regression test covering three cases:
  - dict alias without 'hidden' key (no KeyError, returns info)
  - dict alias with hidden=True (returns None)
  - dict alias with hidden=False (returns info)

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.
