fix(frontend): Format actions.ts for prettier compliance

- toggleLlmModelAction now sends migration params (migrate_to_slug, reason, custom_credit_cost)
- deleteLlmModelAction passes replacement_model_slug query param
- fetchLlmModelUsage calls real /llm/models/{slug}/usage endpoint
- fetchLlmMigrations calls real /llm/migrations endpoint
- revertLlmMigrationAction calls /llm/migrations/{id}/revert
- Fix model usage calls to use slug instead of UUID
