docs(swap): add rate limit weights for strategy and multi_swap routes

- order strategy create: POST /v1/trade/strategy/create — weight 1
- order strategy cancel: POST /v1/trade/strategy/cancel — weight 1
- order strategy list:   GET  /v1/trade/strategy/orders — weight 1
- multi-swap already listed; confirms weight 5 (same as swap)
