[No QA] refactor: OptionRowLHN — OfflineWrapper + ProductTrainingTooltip split

[mountiny]

Part of

#89946 — OptionRowLHN compound component decomposition

Step

3 of 12 — depends on #89947 (Provider + context interface).

What

Two extractions in one PR:

1. OptionRow.OfflineWrapper (OfflineWithFeedback.tsx) — wraps OfflineWithFeedback; reads pendingAction and allReportErrors from RowContext.meta; renders children
2. OptionRow.ProductTrainingTooltip (ProductTrainingTooltip.tsx) — split from the existing OptionRowTooltipLayer; switches to a children API (drops the renderChildren render-prop, addressing the intent of #89751)

OptionRowTooltipLayer.tsx is deleted (or reduced to a thin re-export if needed for the transition).

Why

OfflineWithFeedback and the tooltip layer are independent concerns that should not share a file. Dropping renderChildren in favour of children aligns with the "no render-props for static composition" rule.

Acceptance criteria

• OptionRow.OfflineWrapper accepts children, reads offline data from context
• OptionRow.ProductTrainingTooltip accepts children, no renderChildren prop
• OptionRowTooltipLayer file removed or empty re-export
• No visible behavior changes
