Multiple updates and additions

- Added a permission to show or hide update version information on that dashboard as a card that will only show when new update info is available and not yet dismissed.
- Updated Lists so list items added will have their fist letter auto-capitalized
- Updated Lists so list items are searched against the products before being added to the list, so we have store info more commonly in lists
- Updated Products so new products will have their first letter capitalized automatically
- Updated the dashboard to show the Update Available card if this is enbaled in permissions.
    - The dashboard card only shows for System Admin roles.
    - The dashboard card is enabled by default
    - The dashboard card is pulled from the GitLab releases RSS feed.
    - The RSS Feed is only checked every 30 minutes using node-cron
- Updated System Configuration to have a toggle for the update available card
- Added a bell icon to the top and slide out navigation, shown when a new update is available, if update available is enabled in system configuration.
