Rewrite the TP-Link v9 installer to not use JavaScript

### What problem does this feature solve or what does it enhance?

issues #652 #608 are only caused by various race conditions in our JavaScript code, affect a lot of users, and are frustrating to deal with.

### Proposed Solution

port the entire thing to rust like we did with the orbic-network installer in #635. the tplink installer should then probably take a `--admin-password` parameter as well.

like with orbic-network, this requires reverse-engineering the webserver binary with ghidra.
