fix: change pre-installed snaps order

[Prithpal-Sooriya]

Description

This resolves a weird issue where the TRON snap is not loaded on startup causing issues with Asset Balances for TRON. This is first time install issue, closing and opening fixes. Convo here: https://consensys.slack.com/archives/CTQAGKY5V/p1779204701371199

But the underlying issue still needs debugging.

1. Is the background waiting for all snaps to load before initialising engine, or are there floating promises?
2. Why does this order changing resolve our issues, is there a recent change on the Tron Snap?

We have a longer term, improved, fix on our Assets Controllers side here: MetaMask/core#8862

---

EDIT

Doing some digging, the preinstalled snaps are installed correctly inside the background.js with no floating promises.
However the SnapController.init() - which processes these preinstalled snaps - is a floating promise.
So while all other controllers are loading, the SnapController may not have finished its init().

• Front loading the non-evm snaps biases the startup reducing the chance of missing non-EVM snaps on first install.

Manual testing steps

1. Fresh app install
2. Navigate to TRON
3. EXPECTED: see if TRON native tokens are available.

Hey @Prithpal-Sooriya thanks for the fix, it resolves the issue on Tron but I am still not able to import on Solana. I think it's related?

Thanks @NidhiKJha replied in our slack thread. Was another unrelated change due to a recent accounts-api network addition that caused a behaviour regression

Definitely strange, but seems like a benign change.
