-- Resolves module-relative UI paths in Lua before they reach the C++ layer.
--
-- Root cause being worked around: ResourceManager::resolvePath() resolves a
-- relative path against g_lua.getCurrentSourcePath(), but when the call happens
-- inside a callback (UI button, protocol packet, scheduled event) that context
-- can be unavailable — and the isPreDrawing() branch skips it entirely — so
-- 'file' resolves to '/file.otui' (the root) and the load fails. This breaks
-- every g_ui.loadUI/displayUI/importStyle('barename') call made from a
-- callback (imbuing, outfit, console channels, VIP add/edit, shop, stash,
-- character list, ...), while the same call works from a module's init().
--
-- The fix: wrap the three entry points and, when the argument is a relative
-- path, resolve it against the *calling file's* directory (debug.getinfo),
-- but only if the target file actually exists there. In every other case the
-- argument is forwarded untouched, so behavior is identical to before.
