refactor(medications): split the dose-history ledger into its hook, row and dialogs

The ledger file held two components of 404 and 314 lines. It now reads:

- dose-history/use-dose-history-ledger: the window read, summary, day
  groups and the optimistic mark, plus the owner's edits (toggle, pin,
  release, delete) and one reconcile step after every write
- dose-history/ledger-row-item: the row and, apart from it, the owner's
  row menu
- dose-history/ledger-summary-chart and ledger-confirms

dose-history-ledger.tsx keeps the ledger layout. Markup and behaviour
are unchanged; the guards name the modules that now hold what they
check.
