[No QA] refactor: OptionRowLHN — DraftIndicator + PinIndicator subcomponents

[mountiny]

Part of

#89946 — OptionRowLHN compound component decomposition

Step

11 of 12 — depends on #89947 (Provider + context interface). Incorporates work from #89754.

What

Two extractions in one PR:

1. OptionRow.DraftIndicator (DraftIndicator.tsx) — pencil Icon; renders when hasDraftComment && optionItem.isAllowedToComment; reads from RowContext
2. OptionRow.PinIndicator (PinIndicator.tsx) — pin Icon; renders when !brickRoadIndicator && optionItem.isPinned; reads from RowContext

Both carry their own accessibilityLabel (translated inside the component).

Why

Draft and pin indicators are mutually exclusive decoration icons that should each be self-contained. This carries forward the intent of #89754.

Acceptance criteria

• Each indicator owns its render guard and accessibility label
• Pencil and Pin icon logic removed from OptionRowLHN.tsx
• No visible behavior or style changes
