Fix state_attr_translated to preserve original type for non-string attributes

[Copilot]

state_attr_translated was unconditionally casting attribute values to str before translation lookup, meaning numeric/boolean attributes would silently change type (e.g., 42 → "42") even when no translation existed — breaking template comparisons.

Changes

• StateAttrTranslated.__call__: Skip translation and return the original value unchanged when attr_value is not a str or Enum; only those types have meaningful translation keys
• Return type: Updated from str | None to Any to reflect that non-string values pass through unmodified
• Tests: Added coverage for numeric and boolean attributes confirming type preservation

Example

# Attribute: numeric_attr = 42
# Before: returned "42" (string) — breaks `== 42` comparisons
# After:  returns 42 (int) — type preserved when no translation applies
{% if state_attr_translated("sensor.foo", "numeric_attr") == 42 %}  {# now works correctly #}
