Improve log rotation, early-exit find_bundle, fix uninstall orphaned backup

apply.sh: preserve two log generations (.1 and .2) on rotation so the
last two boots are always available for diagnosis.

patch_ui.py: find_bundle returns on the first matching JS file instead of
collecting all matches. The multi-match warning was dead weight — the Angular
Ivy compiler produces exactly one bundle and the WARNING path was unreachable
in practice.

uninstall.sh: restore an orphaned sitecustomize.py.pre-truecloud-patch when
sitecustomize.py itself has already been removed (e.g. manual deletion while
the backup survived). Prevents leaving ghost vendor files in site-packages.
