This diff handles moving all of the deep link handling logic into the one. The main thing here is we use both parse methods (`parseSecretFromInviteLinkURL` and `parseKeysFromQRCodeURL`) on the current link, and then handle what to do based on whether the regex finds a match. We check for the invite link first because it is possible in theory for there to be an invite link like `/invite/qr-code/` if the community is called `qr-code`, but it's not really possible for the QR code link to contain an `invite` route.
**This is not part of a monthly goal, just a follow-up task.**
Depends on D9027
