feat: improve Settings page retry config UI and enhance excludedModels API support

- Reorganize retry settings into separate Card for better visual hierarchy
  - Move retry update button inline with input field via rightElement
  - Add excluded-models serialization in provider key configuration
  - Add excluded-models normalization support in API transformers with fallback parsing
