fix(model_switch): enumerate dict-format models in /model picker

Browse source 
list_authenticated_providers() builds /model picker rows for CLI, TUI and
gateway flows, but fails to enumerate custom provider models stored in
dict form:

- custom_providers[] entries surface only the singular `model:` field,
  hiding every other model in the `models:` dict.
- providers: dict entries with dict-format `models:` are silently dropped
  and render as `(0 models)`.

Hermes's own writer (main.py::_save_custom_provider) persists configured
models as a dict keyed by model id, and most downstream readers
(agent/models_dev.py, gateway/run.py, run_agent.py, hermes_cli/config.py)
already consume that dict format. The /model picker was the only stale
path.

Add a dict branch in both sections of list_authenticated_providers(),
preferring dict (canonical) and keeping the list branch as fallback for
hand-edited / legacy configs. Dedup against the already-added default
model so nothing duplicates when the default is also a dict key.

Six new regression tests in tests/hermes_cli/ cover: dict models with a
default, dict models without a default, and default dedup against a
matching dict key.
