Add Quick Connect authorization to Settings (#820)

## Description
- Adding `Quick Connect` drawer to the Settings under the Seer
integration, and before Additional options.
- When interacted with, A inline-dialog appears (after internally
resetting itself), with gutter options Cancel / OK, like existing
dialogs, and when that is completed, where it completes the other side
of `Quick Connect`, e.g. login to your phone Jellyfin app by using
Wholphin.
- Failure and success both are indicated to the user and if success, it
closes the window.

Performed several logout/login, both success and fail to observe dialog
state and function.

Used Claude Sonnet 4.5 for most of the code, ChatGPT, reviewed it, then
I reviewed it, made a few tweaks.
