Is it permissible for the aforementioned sister to observe her iddah (waiting period) in her parents' home or at her distant workplace, and is it permissible for her to request a consensual postponement of the divorce until the summer holiday?

The waiting period (iddah (definition)) begins from the moment the divorce occurs and ends after three menstrual cycles for a menstruating woman, upon delivery for a pregnant woman, and after the passage of three months for a non-menstruating woman or one who has reached menopause. A woman observing the iddah is not permitted to spend the night outside her home except out of necessity, though she may go out during the day for a need. If she resides in her parents' home because the husband did not provide a dwelling, then she must observe the iddah there. There is no objection to a mutual agreement between the spouses to divorce at a specific time, but the wife remains under her husband's legal marital bond until the divorce is officially pronounced.
