[BUG] High CPU use in background when a 2FA-bearing entry is selected

[erikrose]

Preliminaries
I have ensured that:

• I am running the latest version of Strongbox on the App Store by searching for Strongbox and clicking into it to see the Update button (or not)
• I have performed a full restart of my device no matter how annoying that is

Versions

• OS: macOS 15.6.7 and 15.7.1

** Strongbox Version **

• Version: 1.61

Describe the bug
When an entry is selected such that a 2FA code is shown in the right-hand pane, Strongbox continually burns about 38% of a CPU in the background (on an M3 Max), as reported by Activity Monitor. When a different entry is selected, the CPU use immediately drops to 1%.

To Reproduce
Steps to reproduce the behavior:

1. Open a database.
2. Click an entry that has a 2FA code.
3. Measure CPU use.

Expected behavior
CPU use is on the order of 1%, no matter what entry is selected.

Additional context
If I were to make a wild guess, it would be that the "ticking" animation is going at too many frames per second.
