refactor(di): migrate Integrations + IPC layer to ILogger<T> (DI-4 Slice B)

Seven services across Integrations/, Ipc/ and GameFunctions/ shift
from Plugin.LogProxy to Microsoft.Extensions.Logging.ILogger<T>.

Files with live LogProxy sites (10 in total):
- Ipc/ExtraChat (1)
- GameFunctions/Chat (6)
- GameFunctions/GameFunctions (2)
- GameFunctions/KeybindManager (1)

Foundation-touch files (no current sites, ctor takes ILogger<T> as
seed for the v1.5.7-11 Plugin-Integrations wave):
- Integrations/HonorificService (also drops the local IPluginLog
  _log field in favour of ILogger<HonorificService> _logger; the
  three _log.* calls there are migrated as a bonus since the field
  had to change anyway)
- IpcManager
- Ipc/TypingIpc

GameFunctions takes ILoggerFactory as an extra ctor arg so it can
hand a typed logger to its nested Chat and KeybindManager (same
pattern MessageStore + MessageEnumerator use in Slice A).

PluginHostFactory factory lambdas updated for all five Slice B
services that need extra resolves.

Plan drift D8: GameFunctions.TryOpenAdventurerPlate is an internal
static method whose only Warning call cannot reach the instance
_logger. The one site stays on Plugin.LogProxy with an inline note;
promoting it to instance + PayloadHandler.cs:814 call-site update is
a v1.5.1+ cleanup, out of DI-4 Slice B scope.
