feat(bookkeeping): show who committed a verifikat, and mark agent work in Granskning history (#1591)

Flows build plan prereq 3 (provenance display). Pure UI over columns that
have existed since migration 20260619120000:

- types: JournalEntry gains committed_actor_type/committed_actor_label
  (the detail/chain APIs already select('*'), the type just lacked them)
- voucher detail: new "Bokford av" row in the Details card, derived from
  actor type + credential label, with the Bot mark for non-user actors
- Granskning Historik rows get the same actor circle pending rows have
  (Bot vs ClipboardCheck) so agent-originated history reads at a glance
- run-turn: correct the staged_operation params comment (tool-use input
  is a superset of pending_operations.params, not the same values)
