feat: add shade capabilities, velocity control, and cleanup

Add ShadeCapability lookup to replace hardcoded model string checks for
tilt/tilt-only selection. Add velocity number entity (0–100) and pass
velocity through all movement paths including open/close. Remove
redundant device_info property overrides and deduplicate hex parsing.
