auth: implement a full pam conversation (#205)

Browse source 
* auth: implement a full pam conversation

* input-field: fixup failedAttempts and color change

Credits to @bvr-yr

* pam: set default module to hyprland

* input-field: backup previous asset

* auth: restart auth in onPasswordCheckTimer

* auth: immediately switch to waiting when input was submitted

* auth: remove redundant waitingForPamAuth

* auth: add inputRequested and reschedule submitInput

* auth: clear password buffer and handle submitInput before input is requested

* Revert "input-field: backup previous asset"

This reverts commit 89702945be6af4aa43f54688ad34a4ccba994a3e.

Without the backup we avoid rendering the prompt placeholder for one frame when the failText is not available.
Looks better this way.

* auth: fallback to su if pam_module not in /etc/pam.d

rare occasion where a path check even works on nix

* auth: rename inputSubmitted and resubmit callback

* auth: detach failText from the conversation

* fix rebase mistake

* auth: make sure prompt and failText are not reset when restarting auth

needed for labels

* auth: force update timers when the prompt changes

* auth: remove unused stuff
