v1.2.0 - Numeric Rounding Support

Adds the ability to control decimal places for numeric sensor values.

New Feature:

• Configure decimal places (0-10) for numeric sensors globally or per-entity
• Example: decimals: 1 shows "72.5" instead of "72.456789"
• Works with templates and default display
• Per-entity override support

Example:

type: custom:indicator-grid-card
decimals: 1
entities:
  - entity: sensor.temperature
    # Shows "72.5" instead of "72.456789"
  - entity: sensor.humidity
    decimals: 0  # Override: no decimals
