refactor(di): migrate UI Window-Layer to ILogger<T> (DI-4 Slice C)

Six UI files shift from Plugin.LogProxy to ILogger<T> via
constructor injection.

Container singletons (each takes a typed ILogger plus, where it owns
nested allocations, an ILoggerFactory to spawn child loggers):
- Ui/ChatLogWindow (15 sites, plus an ILoggerFactory for the
  Popout new-call at Ui/ChatLogWindow.cs:2417)
- Ui/Settings (SettingsWindow): no own sites, but takes an
  ILoggerFactory so it can hand typed loggers to its three migrated
  settings tabs (General, the other six tabs stay unchanged)
- Ui/DbViewer (3 sites)

Nested instances allocated by parent containers:
- Ui/Popout (7 sites, ILogger<Popout> as the new 4th ctor arg passed
  from ChatLogWindow)
- Ui/SettingsTabs/ThemeAndLayout (1 site)
- Ui/SettingsTabs/FontsAndColours (1 site)
- Ui/SettingsTabs/DataManagement (15 sites)

PluginHostFactory factory lambdas updated for ChatLogWindow,
SettingsWindow and DbViewer to resolve the new logger args.
