feat(battle-engine-port): M2 COMPLETE — vanilla follower resolves headless (go/no-go = GO)

First green: a zero-skill vanilla follower (100011010, neutral 1/2) resolves to
correct authoritative state HEADLESS via IsForecast/IsRecovery + ActionProcessor.
PlayCard (DP4), no Unity runtime. §5 oracle passes (PP-cost; hand->in-play;
atk/health == CardCSVData base; opponent unchanged; no exception). VERDICT: the
port approach is validated through the resolution path, not just M1's compile path.

VanillaFollowerOracleTests.Vanilla_follower_resolves_to_correct_state — GREEN.
HeadlessCardMaster now loads the follower's real id from cards.json.

Resolution-path shim/engine gaps closed (all mechanical no-op fills or data seams,
never a Unity/logic wall):
- M1 mis-cut copies (DP1/DP3 — pure no-op logic wrongly stubbed to null):
  Engine/Wizard.Battle.View.Vfx/NullCardVfxCreator.cs (its GetInstance() singleton
  was nulled) + its dep NotEmptyNullVfx.cs. Deleted the generated NullCardVfxCreator
  stub + its _IfaceImpl block; both manifested, check_drift clean.
- _IfaceImpl explicit-impl shadow: interface-typed view/mgr calls dispatch to the
  explicit impls (which returned default!), shadowing public stubs. Fixed
  IBattlePlayerView.GetSideLogControl (SkillProcessor side-log tail) to return a
  non-null no-op. KEY M3+ learning: fix _IfaceImpl.g.cs for interface-typed NREs.

(GameMgr/component-model/Resources/IClassBattleCardView shim fills + CardIconControl
copy + the SVSim.BattleEngine.Tests project landed in the prior commit 2b50657.)
