What is the jurisprudential position regarding the circumambulation of Ifadah (Tawaf al-Ifadah), the throwing of the pebbles (Ramy al-Jamarat), and the farewell circumambulation (Tawaf al-Wada') for a female pilgrim who performed the obligatory Hajj and did not stipulate a condition at the time of Ihram, then was involved in an accident that prevented her from completing the rituals, and she is 85 years old and unable to travel again?

If someone forgets the Farewell Tawaf (circumambulation), or performs it in a way that is not valid, or is prevented from performing it by an impediment, and they have already stood at Arafat, then they must return to perform the Tawaf, because it is a pillar that cannot be compensated for by a sacrifice (dam). If they omit the Sa'i (ritual brisk walking), they must perform it after their Tawaf and remain in the state of ihram until they perform the omitted pillar. As for things other than the pillars, a single sacrifice is sufficient for them.

If a woman suffers an accident or illness after standing at Arafat and before performing the Tawaf (definition) al-Ifadah, throwing the pebbles (rami al-jamarat (definition)), and the Farewell Tawaf, and she reaches an age where she is unable to return and complete her Hajj, then she must appoint someone to perform the remaining pillars of her Hajj on her behalf, as proxy is permissible for pillars for those who are unable to perform them themselves.
