tools: Centralize GPU group setup via setup_hwaccel

improve hardware-acceleration setup to centralize service user group management. Install scripts (emby, plex, ollama, channels) now pass a service user to setup_hwaccel (or no user for channels) and have had inline /etc/group sed/usermod tweaks removed. misc/tools.func updated: setup_hwaccel accepts an optional service_user and forwards it to _setup_gpu_permissions, which now adds the service user to render and video groups if provided. This consolidates GPU permission changes in one place and removes duplicated per-service group edits.

 # ------------------------------------------------------------------------------
-# Get latest GitHub tag for a repository.
+# Fetches and deploys a GitHub tag-based source tarball.
 #
 # Description:
-#   - Queries the GitHub API for tags (not releases)
-#   - Useful for repos that only create tags, not full releases
-#   - Supports optional prefix filter and version-only extraction
-#   - Returns the latest tag name (printed to stdout)
+#   - Downloads the source tarball for a given tag from GitHub
+#   - Extracts to the target directory
+#   - Writes the version to ~/.<app>
 #
 # Usage:
-#   MONGO_VERSION=$(get_latest_gh_tag "mongodb/mongo-tools")
-#   LATEST=$(get_latest_gh_tag "owner/repo" "v")          # only tags starting with "v"
-#   LATEST=$(get_latest_gh_tag "owner/repo" "" "true")     # strip leading "v"
+#     fetch_and_deploy_gh_tag "guacd" "apache/guacamole-server"
+#     fetch_and_deploy_gh_tag "guacd" "apache/guacamole-server" "latest" "/opt/guacamole-server"
 #
 # Arguments:
-#   $1 - GitHub repo (owner/repo)
-#   $2 - Tag prefix filter (optional, e.g. "v" or "100.")
-#   $3 - Strip prefix from result (optional, "true" to strip $2 prefix)
-#
-# Returns:
-#   0 on success (tag printed to stdout), 1 on failure
+#   $1 - App name (used for version file ~/.<app>)
+#   $2 - GitHub repo (owner/repo)
+#   $3 - Tag version (default: "latest" → auto-detect via get_latest_gh_tag)
+#   $4 - Target directory (default: /opt/$app)
 #
 # Notes:
-#   - Skips tags containing "rc", "alpha", "beta", "dev", "test"
-#   - Sorts by version number (sort -V) to find the latest
-#   - Respects GITHUB_TOKEN for rate limiting
+#   - Supports CLEAN_INSTALL=1 to wipe target before extracting
+#   - For repos that only publish tags, not GitHub Releases

+#   - If newer, sets global CHECK_UPDATE_RELEASE and returns 0

+# Notes:
+#   - For repos that only publish tags, not GitHub Releases
