[BUG] Brief flash of subscription UI

[infotexture]

Describe the bug

When launching the app on both macOS and iOS, the subscription UI appears for a split second before Tact seems to recognize the account and proceed to the last open chat.

Environment

• Tact version: Version 1.10.1 (541)
• Hardware: M1 MacBook Pro, iPhone 13 mini
• OS version: macOS Sonoma 14.7.2, iOS 18.2 (Build 22C152)

To reproduce

Steps to reproduce the behavior:

1. Close or force-quit the app if it's already running
2. Launch Tact
3. Don't blink 😉

Expected behavior

Tact should recognize immediately that I have an active subscription and take me right to the last chat.

Observed behavior

The subscription UI appears just long enough for me to wonder if Tact has somehow forgotten that I have a subscription.

Before I can read the words on the screen, Tact recovers and shows me my chats.

Sometimes this happens very fast, and other times the subscription UI seems to linger a bit longer.
I grabbed a stopwatch to time it today, but it was over before I could start/stop the timer, so less than a second.
