New mod: Tray Utility Customizer

[sb4ssman]

Adds Tray Utility Customizer (v1.0): arranges the low-frequency Windows 11 tray utility controls — Show hidden icons (overflow chevron), Emoji and more, touch keyboard, pen menu, virtual touchpad, and the input indicator — into one compact row, column, or smart grid.

Highlights:

• Moves the native tray hosts instead of drawing replacement buttons or forwarding clicks; controls, flyouts, and tooltips stay Windows-owned. Placement is margin-based so flyouts anchor at the control's real position.
• Smart automatic grid sized from the item count and current taskbar height (great for double-height taskbars), plus single row/column and fixed grid modes with fill order and short row/column placement and alignment.
• Position by borrowing the hidden-icons or Emoji column, or by leasing a dedicated, marker-tracked tray column (before icons / before network-volume-battery / before or after clock / after Show Desktop). Two experimental Start-adjacent positions relocate the group beside the Start button.
• Reacts to live changes: utilities toggled off in taskbar settings or transient controls (touch keyboard) release their cell and the grid re-adapts and re-centers automatically.
• Fully reversible: snapshot-and-marker restore returns every host to its native column, size, and alignment on unload.

Screenshots (also embedded in the mod readme):

Tested live on Windows 11 (primary taskbar): default configuration, smart grid on single- and double-height taskbars, borrowed and dedicated positions, flyout/tooltip/right-click behavior, settings reload, taskbar-settings toggles of managed utilities, Explorer restart, and disable/unload restore.
