build(android): build and sign a release, without the password touching anything

Browse Source 
build-apk.ps1 -Release builds the Release configuration and signs with the
user's keystore. Not through Delphi's Provisioning page, for three reasons:
the .dproj is versioned, paclient --apksign puts the password ON THE COMMAND
LINE where any process on the machine reads it, and tooling belongs in the
repository rather than hidden in an IDE setting. apksigner called directly
accepts --ks-pass env:.

The password is asked for with Read-Host -AsSecureString - nothing echoed,
nothing left in console history - handed over through an environment
variable, and removed in a finally even when the script fails.

It prints the certificate it signed with. A release signed by accident with
the debug key installs and runs: nothing tells it apart in use, and one finds
out only when the first update is refused.

It does not install the release. Android refuses a different signature on an
existing package, and uninstalling would wipe the local cache and the
device's settings - a deliberate act, not a script's side effect.

Keystores are gitignored. The debug path is unchanged and still builds.
