Addressed issue where the "See more..." button wasn't aligned with the rest of the items in the `ChatThreadList`. Also changed font size of "See more..." to `12px` per Ben's suggestion (in Linear task linked below).
I saw that Ben and Ashoat mentioned the height of the sidebar item changing in the Linear issue. I'll defer to a later diff to refactor the styling of the "See more..." button if the height change of the sidebar affects anything there.
