fix(updater): never throw from an auto update check (#5028)

Browse source 
checkForAppUpdates runs fire-and-forget on reader/library mount, but it threw on
any network failure: the desktop check() propagated "error sending request for
url (...latest.json)" (READEST-J) and the Android branch re-threw "Failed to
fetch Android update info" (READEST-22). Both surfaced as unhandled rejections.
Wrap the check so a failure is swallowed (returns false) for an auto-check;
manual checks (About window) still surface the error. Adds regression tests.

Fixes READEST-J
Fixes READEST-22
