Add new routes for the proposal notifications edition and
abilities to let moderators edit it (mark as ignored, hide, etc.).
The notifications are not flaggable because they doesn't work like that,
but in a similar way. The moderator/administrator is in charge of hidding
them through the UI, so the normal users don't flag it as inappropriate.
New controller Moderation::ProposalNotification to manage the moderators
work.
The back button when the user changes the password
(in the print password page) redirects to the
edit manually page.
The routes to access password edit pages has been added,
along with the ones to send reset password email and
reset password manually.
Running test suite the following appears: DEPRECATION WARNING: Defining
a route where `to` is a symbol is deprecated. Please change
`to: :json_data` to `action: :json_data`.
During a Participatory Budget, some users are getting confused and
creating a proposal instead of a budget investment. This intermediate
page should help them create investments
Adding a feature flag just in case other forks don’t need this feature
