手机底部Tab and 右侧悬浮按钮 settings pages swap their icon text inputs
for the shared FaIconPicker (with a new IconValue preview component that
renders FA/sprite/custom SVG values in lists and previews). footer.php
tabbar/floating/sub-item icons and the VIP float render through
aksrt_icon_markup so every stored format displays; GlobalControllerPart1
and the VIP helper drop the FA-only regex gate and sanitize icon values
through aksrt_sanitize_icon_value. The picker popover tabs now wrap
instead of overflowing, and FA grid previews use style-only classes.
Mirror the reference theme's universal picker on FA5: a generated full
catalog of the bundled FA5 Free 5.15.4 fonts (src/Icons/fa5-icons.php,
generated from the shipped CSS + SVG fonts), a zibsvg group parsed from
the runtime sprite so it cannot drift, and GET /aksrt/v1/icons/catalog.
Shared admin pieces: aksrt_icon_markup()/aksrt_sanitize_icon_value()
with an SVG allowlist, the picker field/modal assets, and one canonical
aksrt-font-awesome handle registered through aksrt_enqueue_fontawesome().
