refactor(claude-desktop): simplify model mapping UX

- Remove "Import from Claude" button from main provider list (keep in empty state)
- Remove "Desktop model" column from proxy mode mapping table; route names are now auto-generated
- Rename "upstream model" label to "requested model" and equalize column widths
- Rewrite model mapping hint and toggle description for end-user clarity
- Update validation messages and remove dead i18n keys (routeModelLabel)
