Align public reader names with the final AssetsController-oriented API:
getAccountAssets, getAccountAssetsByIDs, getAccountAssetByID.

Handler folder move requires importing from ../cronjob/cronjob rather
than the bare folder path so the Snap bundle resolves correctly.

Handler files moved into subfolders in WPN-1497, so point eslint
suppressions at the new paths and refresh snap.manifest.json after
the handler import path fix changed the bundle hash.

Move existing assets logic into SnapAssetsAdapter and keep AssetsService as a
thin facade that always delegates to the Snap adapter. Behavior unchanged;
prepares for a later Core adapter / feature-flag routing PR.

Adapter lives one directory deeper than AssetsService; bump client,
constants, and types imports to ../../../ and ../types respectively.

Update the manifest shasum, cover AssetsService facade delegation in tests,
and use SnapAssetsAdapter.isFiat inside the adapter implementation.

Move import suppressions to SnapAssetsAdapter and align test assertions
with jest prefer-strict-equal rules.

The previous shasum was generated on macOS and did not match the bundle
produced by CI on Linux, causing dirty-working-tree failures in build and test.
