Debug mode allows route integration tests to raise explicit exceptions on
errors, instead of returning error pages. Some portions of the test
suite need to be able to ignore exceptions (the response is not under
test) so they use a separate pytest fixture version of the app and
client that are configured with debug disabled, as it would be in
production.
`user_can` function built for Jinja template contexts should check
application, portfolio, and atat level permissions depending on what
resources are available on `g`.
A `before_request` hook queries the database for portfolios, requests,
and task orders based on the route arguments. The resources are added as
attributes on `g`. The portfolio context processor and the access
decorator now rely on those resources being available on `g`.
WIP: find major resources in before_request hook, apply to g
WIP: use g.portfolio for portfolio context processor
WIP: the access decorator should rely on the resources being available on g
