   MwProviderTicketMergePanel (mw-pm-*)
   Two-sided wire-field comparison of a stored provider mirror vs the provider's
   fetched live record, with per-field keep-ours / take-theirs resolution.
   Rendered inside grid detail rows (Entitlements provider pane).
   Color language borrowed from the merge editor: warning = conflict,
   info tint = the chosen side.
