XP11: whole suite on net40 — Console + vPOD run on XP SP3 through Win11

The Launcher's XP11 port (8730b9b) now extends to everything: one net40
flavor across Console, vPOD, Contract, and SecureConfig (Newtonsoft.Json
everywhere; the net48/System.Text.Json legs and their #if splits are gone
since nothing consumed them).

Console (net40, single TFM like the Launcher):
- The ~31 BinaryFormatter bitmap blobs in the .resx files became raw
  embedded files under assets/icons/ (extracted byte-faithfully via a
  serialization surrogate — the animated square_throbber.gif survives),
  loaded by Properties.Resources.EmbeddedBitmap/EmbeddedIcon. Reason:
  System.Resources.Extensions' DeserializingResourceReader is net461+
  and cannot load on net40. Strings stay in the .resx.
- IReadOnlyList -> IList in AppRegistry (net45+ interface).

vPOD (net40, single TFM):
- Zip extraction now shares the Launcher's MiniZip.cs (linked source), so
  the diff-test install round-trip exercises it against ZipArchive zips.
- RPC args as JTokens; LaunchApps.json persistence via Newtonsoft;
  Thread.VolatileRead instead of Volatile.Read.

Contract/SecureConfig: net40-only; Client/** (PodManagerConnection) now
ships in the one build. The Launcher package gains
TeslaSecureConfiguration.dll as a dependency of the client half.

Tests: the net48 xunit host loads the net40 assemblies (both CLR4), so
the suite exercises exactly what ships — 106/106 green. Also verified
live: net40 console provisioned, managed, and ran a full RP mission
against net40 vPOD (beacon/passphrase/RSA, 53290 RPC, egg load,
Run/Stop Mission).

Version: 4.11.4.3 across Launcher, Console, and vPOD (vPOD joins the
suite version line; was 1.0.0). Ship the dotNetFx40 redistributable in
Launcher/assets for XP-era pods.
