v0.4.6

Fixed

• AC Charge Speed options now read from device TSL at runtime: Options and values are no longer hardcoded — populated dynamically from the device's own TSL enum spec at startup. Correct labels for every Pecron model automatically. Falls back to 20%/40%/60%/80%/100% if TSL is unavailable.
• TSL no longer re-fetched on every poll: Cached per product key after first fetch, reducing unnecessary API calls.
