Fix the CD wine build and add per-part toggles

The Windows NSIS step failed under wine for two reasons: no X display
(nodrv_CreateWindow) and missing 32-bit libraries (failed to load
syswow64\ntdll.dll). The job now installs xvfb + wine32:i386 and runs the
desktop build under xvfb-run, with Gecko/Mono lookups disabled.

Also add `images` and `desktop` dispatch inputs so either half of the CD
can be skipped (e.g. desktop-only or images-only releases).

+# J621 CD — manual release workflow (Actions tab -> "Run workflow").
+#
+# One dispatch does everything; each half can be skipped with the `images`
+# and `desktop` inputs:
+#   * builds and pushes the backend + frontend images (multi-arch, :latest
+#     and :<short-sha>, GIT_HASH baked in for the version pill),
+#   * builds the desktop packages and attaches them (plus the update
+#     metadata) to the Gitea release tagged `desktop-v<package.json version>`.
+#
+# The live update feed (deploy/data/desktop, served by the frontend nginx at
+# /desktop/) is not touched here: it is runtime state on the deploy host and
+# is still published with `deploy/push_desktop.sh --no-build` from a machine
+# that can reach it.
+#
+# Registry login uses a repo PAT with the minimal write:package scope (the
+# Gitea registry rejects the automatic job token, go-gitea/gitea#23642);
+# release creation uses the automatic job token. Jobs run on the user-scoped
+# nitro-ci runner (ubuntu-latest).
