[BUG] - Configuration values take several seconds to appear when editing tunnel

[bobpaul]

Describe the bug
When editing a tunnel, the page loads with empty input fields and it sometimes takes 10 seconds before values populate in the fields. It seems to be worse on a tunnel that's freshly imported and hasn't previously been edited.

Smartphone (please complete the following information):

• Device: Samsung S10e
• Android Version: Android 12
• App Version 3.5.2
• Backend: Userspace

To Reproduce
Steps to reproduce the behavior:

1. Clear app data in WG Tunnel
2. Export zip of tunnels from official Wireguard app and import into WG Tunnel
3. In WG Tunnel Long Press a tunnel so the settings cog appears
4. Click the cog.
5. Click the edit pencil
6. Observe an empty form for "Interface" settings appears. Start counting.

If you skip steps 1 & 2, it still takes a long time at step 6, but it's usually more like 1-2 seconds instead of 10-12 seconds.

Expected behavior
I would expect the form to already be populated as soon as it shows up.

There is always a time lag to load the data of 5 sec. when switching to edit mode.
