The controllers argument no longer requires a ts-expect-error directive, because its type is supplied via generic argument from the source-of-truth for the controllers array (i.e. Controllers).

This ts-expect-error directive is required due to the @metamask/base-controller version mismatch issue that is affecting most of the controller instantiations in the Engine class.
I've put up a preview branch that demonstrates that pinning base-controller to the latest version using yarn resolutions resolves this issue: #10374.
In practice, this directive will be removed as the controller versions in mobile are upgraded.

These are stateChange events that need to be included in this allowlist, but are throwing errors because of misdefined controllers or messenger typing in their upstream source packages.
I have documented the causes in the comments, and the preview branch demonstrates working fixes for these that use yarn patches.
The wallet framework team has created a ticket to address these issues: MetaMask/core#4579. While the updated controllers are being released, the yarn patch fixes could also be cherry-picked from the preview branch.
Here, I have applied ts-expect-error directives to ensure that the ComposableControllerMessenger is defined with the correct allowlist at runtime, even if the associated types are not yet fully defined.

These are stateChange events that eventually need to be included in this allowlist, but are blocked by their controllers lacking a messagingSystem.
These controllers have been upgraded to V2 or are currently in the process of being upgraded. These events should be uncommented as mobile migrates to using the upgraded V2 versions.
The end result of these changes can be seen in the preview branch: https://github.com/MetaMask/metamask-mobile/pull/10374/files#diff-1a656ef42f595bb9c6c1251b29808fd70d31da7a3e1a6e9be85574ad866dc1b0R1508-R1536

This was causing implicit any types to spread throughout the file. See below.

This CurrencyRateController object has been implicitly typed as any since this year-old change, along with all of the state objects destructured in the preceding lines (https://github.com/MetaMask/metamask-mobile/pull/10441/files#diff-1a656ef42f595bb9c6c1251b29808fd70d31da7a3e1a6e9be85574ad866dc1b0R2001-R2033).
Because of this, when the CurrencyRateController class's state type was significantly altered in a breaking change introduced by @metamask/[email protected], the resulting type error was suppressed, causing this runtime bug to go undetected.
The type error is now restored, as a side effect of the any typing of the datamodel class field being fixed.
Previously, there was only one top-level conversionRate property in the CurrencyRateController object that was being modified. I have fixed the logic so that all nested conversionRate properties for all currencies are normalized to 0 if they have a null value. Please let me know if this isn't the expected behavior.

I added a test for this change, but sonarcloud is still complaining that lines 2099 and 2101 are uncovered: e107dc3
