fix(config): correct Hermes-4-405B display label from 7B to 405B (#11861) (#11993)

Fixes a copy-paste label typo (Hermes-4-405B mislabeled "7B") in both the registry and the free-model catalog data, spotted in the #11861 comment thread. TDD: 3/3 tests, generic parameter-size consistency check + exact regression guard.

+- **fix(config):** Nous Research's `Hermes-4-405B` model now displays as "Hermes 4 405B (Nous Research)" in both the provider registry and the free-model catalog, instead of the mislabelled "Hermes 4 7B" ([#11861](https://github.com/diegosouzapw/OmniRoute/issues/11861)) — thanks @Karan825
