fix(gallery): correct Qwen3.5 typo in qwen3.5-27b-claude-4.6 model override (closes #9362) (#9580)

The overrides.parameters.model field referenced 'Qwen3.-27B-Claude-...' (missing the '5'), so model loads failed because the configured filename did not match the file actually downloaded by the entry's files: list ('Qwen3.5-27B-Claude-...').

Aligns the override filename with the files: entries and with the upstream HF repo (mradermacher/Qwen3.5-27B-...).
