ci: sign and publish HardenedPass releases with the fork's own key

Add the fork's release keystore and its signing properties, encrypted
with openssl (aes-256-cbc, pbkdf2) as secrets/keystore.cipher and
secrets/props.cipher; the key is the ENCRYPT_KEY repository secret.
The plaintext files and the master copy never enter the repository.

Rewrite deploy_github_releases.yml for the single FOSS build: on a
vX.Y.Z tag it decrypts the signing secrets, builds the signed release
APK, removes the secrets, and creates a draft GitHub Release with
HardenedPass_<tag>.apk and its SHA-256 checksum using gh, replacing
the archived actions/create-release and upload-release-asset actions.

AGENTS.md records the certificate fingerprint and the procedure.
