feat: refactor Claude API Profiles to Claude Compatible Providers

- Rename ClaudeApiProfile to ClaudeCompatibleProvider with models[] array
- Each ProviderModel has mapsToClaudeModel field for Claude tier mapping
- Add providerType field for provider-specific icons (glm, minimax, openrouter)
- Add thinking level support for provider models in phase selectors
- Show all mapped Claude models per provider model (e.g., "Maps to Haiku, Sonnet, Opus")
- Add Bulk Replace feature to switch all phases to a provider at once
- Hide Bulk Replace button when no providers are enabled
- Fix project-level phaseModelOverrides not persisting after refresh
- Fix deleting last provider not persisting (remove empty array guard)
- Add getProviderByModelId() helper for all SDK routes
- Update all routes to pass provider config for provider models
- Update terminology from "profiles" to "providers" throughout UI
- Update documentation to reflect new provider system
