fix: properly compute global disabled state with array disabled

- Fix disabled array [true] incorrectly disabling entire slider
- Only return true when array length matches values length AND all are true
- Fix isHandleDisabled to check specific index instead of global state
- Add safety check for rawValues being undefined at memo time
