Refactor invitation system and update UI layout

Updated invitation link generation logic to use 'invitePath' instead of 'siteURL' improving the overall invitation system. The changes also entailed multiple updates to the UI ranging from layout modifications to enhanced alerts and descriptions. Additionally, the text and styling of several components, such as the team account settings container and the layout of personal account settings page, were significantly adjusted.
