Configurable token expiry, minor test adjustments

Looks good in general.

I think all tests that pass for me on master pass here, but not all tests pass for me. I'll investigate this further, but feel free to point out failing tests.

Instead of CHANGE you could also just use MODIFY I think (since we're not renaming columns):

For your consideration; this seems like a simple approach: https://stackoverflow.com/questions/58239220/inject-build-timestamp-into-vue-cli-build-output-files-to-verify-deployments-wit

I couldn't find any references to any rounding going on. Given that the values are all in pixels (right?) I would be interested to what these values are rounded to (for my understanding, you can ship it if it works).

Could it be that the problem is not the precision but that offsetWidth does not take any transformations into account? See https://developer.mozilla.org/en-US/docs/Web/API/CSS_Object_Model/Determining_the_dimensions_of_elements

Simplified and tested reverse currency conversion

• Move the openexchangerates api key to where the other api keys are
• Load payment method whitelist from config

Works for me.

Test foreign currency payments and fixed refund handling

Fixed test failures

Checked in the generated exchangerates-CHF.php file.

Addressed remaining comments

Import conversion rates with a command

Addressed comments

Exchange rates are cached for 24h so we can live on the free OpenExchangeRates plan (1000 per month)

This now just converts directly using the exchange rate from openexchangerates.org, without applying any safety margin.

Fixed storing the currency_amount, displaying exchanged amount and centralized currency conversion

phpcs and phpstan fixes

Addressed comments, removed payment methods from whitelist that we don't currently offer
