fix(ci/release): sign the macOS archive with Developer ID, not auto dev signing

The cert import now yields a valid 'Developer ID Application' identity, but
the macOS `xcodebuild archive` step still inherited the project's automatic
'Apple Development' signing via -allowProvisioningUpdates. That made Xcode try
to mint an Apple Development cert (install fails in the CI keychain,
DVTSecErrorDomain -61 'Write permissions error') and locate a 'Mac App
Development' provisioning profile for io.unom.punktfunk (none exists) —
** ARCHIVE FAILED ** before signing even happened.

A Developer ID DMG needs neither: pin CODE_SIGN_STYLE=Manual + the Developer ID
identity + no profile, mirroring what the export step already does. The app is
non-sandboxed and its only entitlement (keychain-access-groups, team-prefixed)
is authorized by the Developer ID team, so no provisioning profile is required.
ENABLE_HARDENED_RUNTIME=YES is already set, so notarization stays happy.
