Bonsai: promote load-warning banners to top-level UI

Multi-instance cache-lock, "Opening Cuts Skipped", and "Arrays With
Missing Children" banners now draw in BIM_PT_tabs alongside the
existing global error / outdated-model banners, so they remain
visible regardless of the active Bonsai tab. The corresponding
blocks are removed from BIM_PT_project. Dead imports
(is_cache_locked_by_other_process, draw_multiline_text) dropped
from project/ui.py.
