GIANTS ModHub retest fixes: GUI profiles and default control

[SimGamerJen]

Purpose

Address the latest GIANTS ModHub retest feedback without changing the mod's intended single-player scope.

Changes

• Replace the layout-dependent KEY_quote default with the modifier combination KEY_lalt KEY_lshift KEY_a (Alt+Shift+A).
• Explicitly set ignoreComboMask="false" for the Avatar Switcher action so the modifier combination behaves as a combo rather than a bare A action.
• Update English, German and French ModHub descriptions using GIANTS' supplied wording, adjusted only so the documented default is Alt+Shift+A.
• Add AS_GuiLifecycle.lua to load gui/guiProfiles.xml exactly once per game process.
• Route both the selector and Wardrobe save dialog through the shared GUI-profile guard, preventing repeated registration of asButtonSaveEnter, asMetaText, asInputFieldButton, asButtonDelete, etc.
• Update README control documentation to Alt+Shift+A.

Why this binding

The original apostrophe/quote binding is keyboard-layout dependent, and F11 proved unsuitable because FS25/debug tooling can bind it to render/debug visualisation functions. Alt+Shift+A avoids those issues and was checked against the current user inputBinding.xml with no exact or shorter modifier collision found for this combination.

Intentionally not changed yet

• <multiplayer supported="false" /> remains unchanged. The mod is intentionally single-player and GIANTS' own requested replacement description explicitly says multiplayer is not supported. We should review this before any attempt to silence TestRunner by advertising unsupported multiplayer compatibility.

Review/test points

1. Start FS25 with a clean log.
2. Confirm Alt+Shift+A appears correctly in Controls and opens Avatar Switcher without triggering another action.
3. Open/close/reopen Avatar Switcher several times.
4. Open the Wardrobe, use Save to AvatarSwitcher, close/reopen the save dialog, then open the selector again.
5. Confirm no GUI-Profile name ... already defined DevErrors are produced.
6. Confirm saving, category selection/creation, applying and deleting presets still work as before.
