feat: extract into remaining packages

There has been a cyclic dependency.
transaction
	-> treasure_chest
	-> transaction_recurring
	-> transaction

This has been temporarily solved by moving the GenerateTransactions

to be rewritten to use a proper Service insteas of direct DB access or
replaced with a different system entirely.
