## Description
When a customer whose Stripe subscription is past due (within the 30 day
window after expiry time and has not been cancelled) clicks on the
subscription modal, take them to the payment portal to complete the
subscription.
## Tests
- [x] Tested web
- [x] Tested mobile
## Description
### Stripe
- Settings have been modified to "Cancel" the subscription if all
attempts to charge an invoice fails. The previous configuration was to
set the subscription to "Past Due".
### Museum
- Updated our Stripe workflow to use `PaymentBehaviorAllowIncomplete` in
case of SEPA payments
- Fixed the issue caused by us spawning unnecessary subscriptions when a
customer tried to renew their expired subscription
- Removed the email that was being sent out when a Stripe subscription
expired. We will have to run our own cron to send a notification and
perform necessary clean up. When payments fail, we will still send a
notification to intimate the customer that their account is on hold.
### Mobile
- Fixed the dialogs and error messages on the payment page
## Tests
The following cases were tested for SEPA, Credit Cards, and Credit Cards
with 3DS.
- [x] Purchase
- [x] Success
- [x] Failure
- [x] Renewal
- [x] Success
- [x] Failure
- [x] Upgrades
- [x] Success
- [x] Failure
- [x] Cancellation
- [x] Resumption post recovery
## Note
These changes are likely to break in the event of some corner cases we
haven't thought of. But this will land us in a state that is better than
where we are right now in terms of collecting payments for expired
subscriptions and those via SEPA.
On desktop, now there Help menu will have an "Ente Help" option instead of "FAQ"
(Unrelated: I noticed that user facing strings in the desktop app are not
localized).
The only place remaining after this is the sidebar on mobile
(`support_section_widget.dart`), but I wasn't sure of what string to use (and
how to add it to the localized strings for mobile) so I've left it unchanged.
## Description

performance.
- Automate email and password entry.
