* fix(romm): remove stale 1.x alembic migrations on update
RomM releases before v2.4 shipped dot-version migration files
(1.6.2_.py, 1.7.1_.py, 1.8_.py, 1.8.1_.py, 1.8.2_.py, 1.8.3_.py,
2.0.0_.py) alongside the 4-digit series. When the romm app is
upgraded from a pre-v2.4 install to a current release, these
files survive in /opt/romm/backend/alembic/versions/ and cause
alembic to fail with 'Multiple head revisions are present for
given argument head', preventing the backend from starting.
Add a defensive cleanup step in the update function that runs
right after fetch_and_deploy_gh_release. The cleanup removes any
leftover 1.x and 2.0.0_ migration files plus cached __pycache__
directories. It is a no-op on clean installs of the current
release, and only affects files in the alembic/versions/ folder.
