The app config JSON carried "myEpApiBaseUrl" from the TypoScript setting
myEpApiEndpointUrl, which only the alvac and cllt sys_template records set:
the other sites rendered the unresolved "{$plugin.tx_eptheme.settings...}"
into the page. No JavaScript reads the key (only paCode and externalDomains
are used), and the MyE&P API client takes its URL, credentials and timeout
from the ep_products extension configuration, so the theme's
myEpApiEndpointUrl, myEpApiToken and myEpApiTimeout settings had no reader.
