fix(atomic): reorder class fields in atomic-insight-result-action to follow convention

[Copilot]

Addresses review feedback on #7172: static styles was declared after @property and @state fields instead of immediately after the class declaration.

Changes

• Reordered class fields in AtomicInsightResultAction to follow the established convention:
  1. static styles
  2. @property() decorated fields
  3. @state() decorated fields
  4. Non-decorated private fields
