fix(model): Support providers: dict for custom endpoints in /model

Browse Source 
Two fixes for user-defined providers in config.yaml:

1. list_authenticated_providers() - now includes full models list from
   providers.*.models array, not just default_model. This fixes /model
   showing only one model when multiple are configured.

2. _get_named_custom_provider() - now checks providers: dict (new-style)
   in addition to custom_providers: list (legacy). This fixes credential
   resolution errors when switching models via /model command.

Both changes are backwards compatible with existing custom_providers list format.

Fixes: Only one model appears for custom providers in /model selection
