Bug with Stripe configs `Save customer payment method`

04/04/2025:
 There is a bug with Stripe config; specifically `Save Customer Payment Method`

Look at this setting:

It has `Expired Authorizations` = `Try to re-create the charge using the same card` 
and `Save customer payment method` = `Enabled via "Expired authorizations" setting`
Even though it says `Save customer payment method` = Enabled; behind the scenes it's actually disabled. If you log in as a front-end customer, the link `Saved Payment Methods` is not shown.

To fix this bug; we need to make sure `Save customer payment method` flag is Enabled.

1/ First, switch `Expired authorization` to `Warn admin and don't capture` and click Save. This helps enable the drop-down for `Save customer payment method`:

2/ Notice that `Save customer payment method` flag is `Disabled`; which caused the bug we saw earlier. Switch it to `Enabled` and click Save.

3/ Now that the flag `Save customer payment method` flag is Enabled; it's ok to switch back `Expired authorizations` to `Try to re-create the charge using the same card`; and click Save.
Behind the scenes, the flag `Save customer payment method` flag was switched to Enabled. 
Verify by going to front-end customer dashboard, the button `Save Payment Methods` is now shown:
