Replaces 18 useCallback wrappers with a typed action union and
encounterReducer. Undo/redo wrapping is now systematic per-case in
the reducer instead of ad-hoc per operation. Complex cases (undo/redo,
bestiary add, player character add) are extracted into helper functions.
The stat block auto-show on bestiary add now uses lastCreatureId from
reducer state instead of the synchronous return value, with a useEffect
in use-action-bar-state to react to changes.

Extract addOneFromBestiary (no undo) and build addMultipleFromBestiary
on top so confirming N creatures from the bestiary panel creates one
undo entry that restores the entire batch, not N individual entries.

Extract useActionBarState hook with all search/queue/mode state and
handlers. Extract RollAllButton (context-consuming, zero props),
BrowseSuggestions, CustomStatFields, and refactor AddModeSuggestions
to use grouped SuggestionActions interface (11 props → 6).
ActionBar is now a ~120-line layout shell.
