Add Synology DSM support (#5315)

Adds optional support for running the playbook on Synology DSM 7+, detected automatically via /etc/synoinfo.conf so that non-Synology hosts are unaffected. Includes DSM-native user/group management (synouser/synogroup), a requests version constraint for Docker SDK compatibility, and a boot-fix service that re-shares the volume mount and starts matrix services skipped by DSM's boot ordering. The shared-mount volume path is configurable via matrix_base_synology_volume_path, and the make-shared step only runs when the volume is not already shared.

+# Boot recovery for Matrix services on Synology DSM.
+#
+# This script runs after multi-user.target (outside Container Manager's dependency
+# chain) and does two things:
+#
+# 1. Makes {{ matrix_base_synology_volume_path }} mount-shared so Docker bind-propagation=slave mounts work.
+#    Inserting this into the systemd chain Before=pkg-ContainerManager-dockerd.service
+#    causes Container Manager to detect a broken dependency and prompt for repair,
+#    so it must run here instead, after Docker is already up.
+#
+# 2. Starts any enabled matrix-*.service that systemd skipped at boot.
+#    Synology's systemd drops services with multi-level dependency chains
+#    (e.g. traefik -> socket-proxy -> docker) from the boot activation queue.
+#    Services that need bind-propagation=slave (e.g. matrix-synapse) are
+#    created after step 1, so the propagation is already in effect.
+
