A more focused details panel

When working with a mentee day to day, having the right context matters. We've reorganized the details panel to bring the most important information front and center.

Here's a summary of what's changed:

1. Current plan: When you open a mentee's conversation, you'll immediately see what plan they're currently on and the payment status.
2. Plan and mentorship actions: You can click the ...   button in the current plan card to make changes to the plan, offer a discount, or pause/finish the mentorship
3. Scheduled changes: If a plan change is coming up, you'll see it displayed as a scheduled change below the current plan, so it's always clear what's active now vs. what takes effect next cycle
4. Notes (previously called Notepad): Your private notes about a mentee now live at the bottom of their profile
