fix(windows): keep online update in focus

chore(windows): fully disable auto start task

The Online Update form did not have the correct owner window for some
operations, meaning that the elevation dialog would not get foreground.

auto: increment beta version to 14.0.260

chore(linux): Move signature files as well

fix(android/engine): Reset in-app context when selection changes

If the registry setting `HKCU\Software\Keyman
Engine\Debug:Flag_UseAutoStartTask[REG_WORD]` is not `0`, then the this
will enable the restart task. Otherwise, all aspects of it are disabled.

For Keyman 14.0 initial release, we will have this flag disabled. If we
can improve stability of it, we'll consider turning it on.

fix(common/models): prevents "undefined" reversion display string

Fixes #4467.

Background: in some scenarios, e.g. files in use, Setup must restart
before it completes. This is particularly the case if kmcomapi.dll is
locked and Windows will move the new version into place after a restart.
In this scenario, we would end up calling the old version of
kmcomapi.dll to install keyboards, etc, which is definitely not
desirable.

Problem: Setup was not saving complete state before the restart, so when
it resumed post-restart, would get a blank slate to work from, losing
command-line options passed in and any choices that the end user may
have made during the installation.

Fix: This PR adds serialization of the `TInstallInfo` state data, so
that the install state can be saved to disk before restart, and reloaded
after the restart. This also means that the `-c` parameter now takes a
filename, being the temporary state JSON file, and when in
"ContinueSetup" mode, no longer needs to perform all the checks it did
previously, making the second half of Setup somewhat faster.

Testing: Added a unit test for the serialization of `TInstallInfo`, and
have tested on a VM in various scenarios without problems.

This fix is somewhat broader than I really like to make while in Beta,
but I don't think there was a viable alternative.
