Fix clicking in status side panel

[stefanhaller]

• PR Description

Clicking in the status side panel should activate it; also, clicking on the repo name should bring up the recent repositories menu, and clicking on the "(rebasing)" text should bring up the rebase options menu. All of this was broken for a long time, since somewhere around the big refactoring of March 2023. (The exact commit where it broke is hard to bisect, since many of the commits in that area either don't compile or crash at startup...)

I'm fixing this not because I think it's super important functionality (nobody seems to have missed it for over a year), but because I have to touch this code in another PR, and noticed that it wasn't working.

• Please check if the PR fulfills these requirements

• Cheatsheets are up-to-date (run go generate ./...)
• Code has been formatted (see here)
• Tests have been added/updated (see here for the integration test guide)
• Text is internationalised (see here)
• Docs (specifically docs/Config.md) have been updated if necessary
• You've read through your own file changes for silly mistakes etc
