Dashboard empty view (#707)

* Added i18n for the Dashboard page.

* Add a check for blank. Empty returned an error since @accounts was nil.

* Remove subtitle when accounts are empty..

* Increased the padding-right value for the buttons. The sapce occupied by the icon made the button elements unbalanced.

* Add refactor as suggested by Zach (https://github.com/maybe-finance/maybe/pull/707#discussion_r1588506443)

* Extract empty state into a partial.

* Render new partial if no accounts exist.

* Moved translation text to shared directory.

* Fix padding-right on New account button.

* Lint fix

* i18n tasks

* Get tests passing with :test queue adapter
