fix: division-by-zero guard, rate-limit wallet endpoints, safer JSON parse, Lighter HTTP checks

Browse Source 
- Guard GridCount-1 division by zero in grid spacing calculation (both grid.go and grid_levels.go)
- Rate-limit /wallet/validate and /wallet/generate endpoints (prevent DoS on key generation)
- Wrap JSON.parse(localStorage) in try-catch in AuthContext (corrupted data → graceful re-login)
- Wrap handleJSONResponse JSON.parse in try-catch with descriptive error
- Add HTTP status code checks for Lighter GetActiveOrders and sendTx
- Replace deprecated strings.Title with cases.Title (golang.org/x/text)
- Reuse HTTP client in checkClaw402Health (was creating new client per call)
