Step 4 of multi-instancing migration. Three additional per-battle statics
front-fronted by BattleAmbient.Current, each with a static fallback for
unwrapped callers. ViewerId's SavedataManager-persisting setter is preserved
on the fallback path; inside a scope, the setter is a no-op (the per-battle
perspective is fixed at scope entry).

Step 3 of multi-instancing migration. The dominant per-battle singleton now
resolves through BattleAmbient.Current.Mgr when a scope is active. The legacy
'main' field is renamed _mainFallback and retained for unwrapped callers
(tests, anything not yet scope-wrapped). GetIns() still returns null when
neither is set, preserving the '?.Foo ?? default' patterns in engine code.

Hygiene fixup for the IsForecast/IsRandomDraw ambient conversion in 3b5f2e1.
The manifest sha was stale (pointed at the pre-ambient RNG-virtual-patched
contents) and the change had no companion .patch artifact alongside
BattleManagerBase.rng-virtual.patch. Follow established convention.

Final three clusters:
- RoomParamKey: copy Wizard.RoomMatch/RoomParamKey.cs verbatim (UriNames/WatchUriNames
static dicts keyed by PlayerController.ROOM_URI + PlayerControllerForWatching.
SEND_PARAMETER — both now real enums).
- CardChooseTask: copy the TwoPick/CardChooseTask.cs (TaskManager `using`s .Arena.TwoPick,
not .Competition — copy_loop had only landed the Competition twin).
- SetCardNumLabel CS1739: decompiler param-name artifact — the local fn's 3rd param was
recovered as `flag` but call sites pass it named `isRed:`. First DP5 tracked patch:
Engine/UICardList.cs edited (flag->isRed, zero logic change), recorded in
Patches/ + manifest patched=1 (drift-clean).
M1 exit criteria met: `dotnet build SVSim.BattleEngine` = 0 errors, no Unity ref in csproj,
check_drift clean. Session 7: 198 -> 0 across waves 7a-7k.
