Resolve "rest of modules in Open translation issues/questions"

adresses in #1058

I found german hardcoding in the store module:

• storecontrol -> l. 78, 102, 132.
• storegateway -> there seem to be lots of german variables but I'd focus on the texts, being seemingly only in ::getStoreStateList
• storeview -> l. 117, 124, 159-170
• storexhr -> l. 104

components:

• storelist.vue -> l17,

and

the in StoreUser module

• storeusercontrol -> l. 228
• storeuserview -> l. 68-70, 90-95, 127-132
