Fix crash on various Settings screen

[itsmeichigo]

Closes: #12656

Description

In #12602 I removed the Dashboard storyboard which contains screens related to the Settings flow. This causes crashes when open Help & Support, Application Log, Privacy, and About screens from Settings.

This PR fixes this by restoring the old Dashboard storyboard. To avoid misunderstanding in the future, I also renamed this storyboard to Settings.

Testing instructions

• Log in to the app.
• Navigate to Menu tab > Settings.
• Select Help & Support and confirm that the app doesn't crash.
• Select View Application Log and confirm that the app doesn't crash.
• Navigate back to the Settings screen and select Privacy Settings. Confirm that the app doesn't crash.
• Navigate back and select WooCommerce in the About the app section. Confirm that the app doesn't crash.

About	Privacy	Help	Application Log

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
