v1.0.1

Changes

• fix by @jmdevita: prevent entities from going unavailable during hourly token refresh
  • Entities now maintain their values during OAuth token refresh instead of temporarily showing as "unavailable"
  • Added caching mechanism to return last known data during temporary failures (rate limits, token refresh, network issues)
• fix by @jmdevita: convert creation_date timestamp to readable date format
  • The "Creation date" attribute in the Etsy Shop Info sensor now shows a human-readable date (e.g., "2025-01-14 05:20:25") instead of a raw Unix timestamp number (e.g., "1,736,821,225")
