feat(admin): finish the screens that were stopping one step short

Five places where the data existed and the screen did not use it. Booking a whole course had no button because it needs a doctor and the course does not carry one — each session can be with a different doctor. The page now asks for the doctor the same way the resource booking page does, and the button explains that it is all-or-nothing before it is pressed. A course whose package does not cover the remaining sessions is still valid — the rest is simply charged normally — but nobody was told. The course response carries package_balance and the shortfall, and the page warns. Before session six, not during it. The credit ledger already returned who recorded a row and which appointment it belonged to, and showed neither. An adjustable ledger without the name of the person who adjusted it is half an audit trail. Version history printed a JSON blob of each version's effects, which does not answer the question anyone actually has: what changed? It now diffs each version against the previous one, field by field, and says so plainly when a version changed nothing meaningful. A resource with no calendar showed "—" for utilization. Null means undefined, not zero, and the next step is always the same: set up the calendar. It is a link now. The report range also accepts a custom from/to, kept in the URL like the rest.
