Port to SQLAlchemy 2

Hi all,

I've just deployed a new LVFS website container that ports from SQLAlchemy =
version 1.4.54 to SQLAlchemy version 2.0.41. This was a significant amount =
of work, with 72 files changed, 1967 insertions and 1665 deletions. I've be=
en testing the new version in staging for a few days and it has been workin=
g well.

If I've done everything properly, you shouldn't notice any changes either i=
n behavior or user interface -- except in some cases it should be a bit qui=
cker to load firmware and component pages.

If you do spot something that looks wrong, or something that doesn't work l=
ike it used to please let me know off-list. Thanks.

Richard.
