Bug description

Yesterday, I attempted to reset my phone. I tried to log into signal. My account does have a registration pin. I went through to the part until it requests a PIN. I entered that and saw a small toast notification saying "Reg lock!" and then it just spins indefinitely. This happened yesterday. I found some old issue saying that the user was probably rate limited and needed to wait 24 hours. I have now waited over 24 hours and tried again and I'm stuck in the same hell cycle. I can't read very important business emails in my signal account. I appear to just be fully locked out. I've tried several times, reset my cache and storage (as well as uninstalled and reinstalled the app). I'm 100% sure I am entering my pin correctly (copy and pasted from my password manager and I've used this pin many times in the past to re-register). Here's the debug log:

Start by reviewing the linked debug log and the registration details in the issue, then reproduce the PIN entry flow on a Pixel 9 XL running Android 16 with Signal 8.9.1. Trace the Reglock path to determine why a valid PIN leaves registration spinning. Done means the registration outcome is handled correctly instead of leaving the user stuck.
