The monogram placeholder wasn't really session-specific — the same hue-from-seed + initials logic fits every target that has an optional bundle icon. Rename `SessionPlaceholder` → `IconPlaceholder` (data in LumaCore) and the two view wrappers to `IconPlaceholderView` so the scope reads correctly, then wire the target picker's app and process rows to fall back on it when no Frida-provided icon is available. Seeds are app.identifier for applications and proc.name for processes so repeat targets keep consistent colours.
