Improved dashboard tables with enhanced date formatting and account controls

Dashboard tables now show compact dates like "Dec 24" with relative times such as "2h" or "3d". Accounts can be toggled between tracked and untracked directly from the table, and a delete option with confirmation is available in the row dropdown. The creators table also gains platform tooltips showing views broken down by platform.

Sidebar icons now have tooltips for easier navigation, and the creators and accounts tables default to showing all records — active and inactive, tracked and untracked — for full roster visibility.
