Add ability to configure round-robin strategy for individual combos,
similar to per-provider strategy overrides.
Changes:
- Add comboStrategies setting to store per-combo strategy overrides
- Add Round Robin toggle to each combo card in combos page
- Update chat handler to check combo-specific strategy before global
- Combo-specific strategy takes precedence over global comboStrategy
When enabled, each request to that combo will cycle through providers
instead of always starting with the first one.
Made-with: Cursor
- Support custom provider models in combos and model selection
- Display custom provider names instead of technical IDs
- Make model fields readonly (selected via modal)
- Only show connected providers (remove fallback)
