Clean up I18n translation paths

[zachgoll]

While we're currently only using en locale for translations, the directory structure and yaml key paths need to be cleaned up.

For example (one of many examples that can be cleaned up):

maybe/config/locales/views/shared/en.yml

Lines 3 to 22 in 5516b03

	custom_turbo_confirm:
	account_destroy:
	accept: Delete "%{name}"
	body_html: "<p>By deleting this account, you will erase its value history, affecting
	various aspects of your overall account. This action will have a direct impact
	on your net worth calculations and the account graphs.</p><br /> <p>After
	deletion, there is no way you'll be able to restore the account information
	because you'll need to add it as a new account.</p>"
	title: Delete account?
	default:
	accept: Confirm
	body_html: "<p>You will not be able to undo this decision</p>"
	title: Are you sure?
	history:
	accept: Delete entry
	body_html: "<p>Deleting this entry will remove it from the account’s history
	which will impact different parts of your account. This includes the net worth
	and account graphs.</p></br><p>The only way you’ll be able to add this entry
	back is by re-entering it manually via a new entry</p>"
	title: Delete Entry?

In this example, the path of the keys should map to the directory structure so we can benefit from lazy lookups in controllers and views.

Tasks

• Make sure translations follow the directory structure of the project
• Make sure i18n-tasks can run all commands (currently it is broken for i18n-tasks add-missing
• ??? (there may be additional cleanup needed)
