feat(vaccinations): add the dose capture and edit form

- one sheet for create and edit, saving with a date and one identity arm
  (catalogue pick or free text); nothing else can block the save
- catalogue picker searches localised names and generic synonyms over the
  static antigen list, never overwriting the free-text arm
- optional dose/series, lot, site, practice combobox, visit suggestion and
  note, all reusing the encounter-form primitives
- write hooks fan out through the dose dependent-keys and the reminder reads
- form/site/sheet copy in six locales
