v1.6.0 - Timer duration editor + UI refinements

What's Changed

• Added an inline duration editor for native timer.* entities (when idle or paused). Click the time/status to adjust the default duration, then Save (update only) or Start (update + start).
• Improved timer list parsing across sources (supports both [id, timer] tuples and object-style timer arrays).
• UI refinements across multiple styles:
  • Circle: progress ring rendering and layering improvements
  • Progress bar (vertical): action buttons placement aligned with prior behavior
  • Background fill (vertical + horizontal): drain behavior and padding/corner rendering improvements
• Theme blending tweaks for icon and background elements for better consistency on transparent or heavily themed dashboards.

Notes

• The native timer duration editor relies on the timer/update websocket API. If your Home Assistant version does not support it, you'll see an error toast and the timer will behave as it did in v1.5.1.

Breaking Changes

• None expected (no config key renames or removals between v1.5.1 and v1.6.0).
