Update theme toggle functionality and UI components

Implemented a new ModeToggle feature for theme switching in personal account dropdown. The changes also made adjustments to several UI components, such as transforming Dialog to AlertDialog in transfer-ownership-dialog, and introducing invitation-submit-button in team-accounts. Some minor amendments include text changes and styling modifications.
