Add a system for upgrading accounts using upgrade codes. Users purchase
an upgrade code off-site then redeem it on-site to upgrade their account
to Gold. Upgrade codes are randomly pre-generated and are one time use
only. Codes have enough randomness that guessing a code is infeasible.
* Fix it so that if upgrades are disabled, only the payment button is disabled instead of the whole page.
* Fix it so that disabling upgrades with DANBOORU_USER_UPGRADES_ENABLED="false" works.
Factor out the Stripe code from the UserUpgrade class. Introduce a new
PaymentTransaction abstract class that represents a payment with some
payment processor, and a PaymentTransaction::Stripe class that
implements transactions with Stripe.
Note that we can't completely eliminate Stripe even though we no longer
accept payments with it because we still need to be able to look up old
payments in Stripe.
Disable the ability to upgrade to Platinum. The Platinum level still
exists, but users can no longer upgrade to it. Sales of Platinum are
being disabled in preparation of increasing the tag limit for Gold
users.
* Add a gap between thumbnails on mobile.
* Adjust CSS for scores and vote buttons.
* Include "Private favorites" as an incentive on the user upgrade page.
* Fix vote buttons not being visible beneath thumbnails on mobile.
* Fix the "Show scores" link not preserving the current page number.
* Fix vote buttons being unintentionally enabled for all thumbnails by default.
* Fix banned and restricted users being able to favorite posts by
tagging them with `fav:self`.
* Fix search engines being able to crawl /posts?view=score pages.
* Fix broken tests.
Let all users have unlimited favorites. Formerly the limit was 10k
favorites for regular members, 20k for Gold, and unlimited for Platinum.
Limiting favorites doesn't make sense since upvotes are unlimited.
Move the BUR help text from the <textarea> placeholder attribute to a
<details> tag that embeds the [[help:bur_notice]] wiki page.
Also update some CSS for the <details> tag that was meant to only apply
to the user upgrades page and didn't look good here.
Refactor CSS to use standard Tailwind-style utility classes instead of
ad-hoc rules. This eliminates a lot of single-purpose rules for specific
UI elements and standardizes margins to be more consistent throughout
the site.
Utility classes are defined manually on an as-needed basis instead of
importing Tailwind as a whole. Naming conventions mostly follow
Tailwind's conventions, otherwise they follow Bootstrap.

* https://getbootstrap.com/docs/5.0/utilities/spacing/
* Refactor various user limit methods to class methods from instance
methods so they can be used outside the context of a single user.
* Remove the Danbooru.config.base_tag_query_limit option.
Allow promo codes to be used during checkout if a secret promo=true url
param is passed. Allows promo codes to be offered without having the
promo code option always appear even when there aren't any active promos.
Add the following bank redirect payment methods:
* https://stripe.com/docs/payments/bancontact
* https://stripe.com/docs/payments/eps
* https://stripe.com/docs/payments/giropay
* https://stripe.com/docs/payments/ideal
* https://stripe.com/docs/payments/p24
These methods are used in Austria, Belgium, Germany, the Netherlands,
and Poland.
These methods require payments to be denominated in EUR, which means we
have to set prices in both USD and EUR, and we have to automatically
detect which currency to use based on the user's country. We also have
to automatically detect which payment methods to offer based on the
user's country. We do this by using Cloudflare's CF-IPCountry header to
geolocate the user's country.
This also switches to using prices and products defined in Stripe
instead of generated on-the-fly when creating the checkout.
Add links to the Stripe payment page and the Stripe receipt page on
completed user upgrades.
The Stripe payment link is a link to the payment details on the Stripe
dashboard and is only visible to the owner.
* Add a frequently asked questions section.
* Add nicer looking upgrade buttons.
* Format the page nicer.
* Prevent users from attempting invalid upgrades on users that are
already Platinum or above.
Add a model to store the status of user upgrades.
* Store the upgrade purchaser and the upgrade receiver (these are
different for a gifted upgrade, the same for a self upgrade).
* Store the upgrade type: gold, platinum, or gold-to-platinum upgrades.
* Store the upgrade status:
** pending: User is still on the Stripe checkout page, no payment
received yet.
** processing: User has completed checkout, but the checkout status in
Stripe is still 'unpaid'.
** complete: We've received notification from Stripe that the payment
has gone through and the user has been upgraded.
* Store the Stripe checkout ID, to cross-reference the upgrade record on
Danbooru with the checkout record on Stripe.
This is the upgrade flow:
* When the user clicks the upgrade button on the upgrade page, we call
POST /user_upgrades and create a pending UserUpgrade.
* We redirect the user to the checkout page on Stripe.
* When the user completes checkout on Stripe, Stripe sends us a webhook
notification at POST /webhooks/receive.
* When we receive the webhook, we check the payment status, and if it's
paid we mark the UserUpgrade as complete and upgrade the user.
* After Stripe sees that we have successfully processed the webhook,
they redirect the user to the /user_upgrades/:id page, where we show
the user their upgrade receipt.
This upgrades from the legacy version of Stripe's checkout system to the
new version:
> The legacy version of Checkout presented customers with a modal dialog
> that collected card information, and returned a token or a source to
> your website. In contrast, the new version of Checkout is a smart
> payment page hosted by Stripe that creates payments or subscriptions. It
> supports Apple Pay, Dynamic 3D Secure, and many other features.
Basic overview of the new system:
* We send the user to a checkout page on Stripe.
* Stripe collects payment and sends us a webhook notification when the
order is complete.
* We receive the webhook notification and upgrade the user.

* https://stripe.com/docs/payments/checkout/fulfill-orders
* Call them hidden tags instead of censored tags so that users don't
think that buying gold removes censorship from images (yes, this happened).
* Remove API ratelimit information (not relevant to most users).
* Replace /session/new with /login and /session/sign_out with /logout.
* Rename 'sign in' to 'login'.
This changes are to make urls cleaner and terminology more consistent.
* Fix the post-upgrade message showing the gift message instead of the
normal upgrade message.
* Link back to Danbooru so people don't stay on Safebooru and get
confused when they can't see hidden posts.
