fix(e2e): wait for the sidebar before counting its links

The suite passed on a laptop and failed on the runner with zero links
found. locator.all() is a snapshot and does not auto-wait: calling it
straight after goto() measures how fast the machine is, not what the page
contains.

An assertion on the first link waits for hydration, and the hrefs are
collected once and re-resolved on each pass rather than held as element
handles — navigating re-renders the sidebar, so a handle from before the
click points at an element that no longer exists.
