* core: add progress; fix exit status
Introduce post_progress_to_api() in alpine-install.func and install.func to send a lightweight, fire-and-forget telemetry ping (HTTP POST) that updates an existing telemetry record to "configuring" when DIAGNOSTICS=yes and RANDOM_UUID is set. The function is non-blocking (curl -m 5, errors ignored) and is invoked during container setup and after OS updates to signal active progress. Also adjust api_exit_script() in build.func to report success (post_update_to_api "done" "0") for cases where the script exited normally but a completion status wasn't posted, instead of reporting failure.
* Safer tools.func load and improved error handling
Replace process-substitution sourcing of tools.func with an explicit curl -> variable -> source via /dev/stdin, adding failure messages and a check that expected functions (e.g. fetch_and_deploy_gh_release) are present (misc/alpine-install.func, misc/install.func). Add categorize_error mapping for exit code 10 -> "config" (misc/api.func). Tweak build.func: minor pipeline formatting and change the ERR trap to capture the actual exit code and only call ensure_log_on_host/post_update on non-zero exits, preventing erroneous failure reporting.
* tools: add data init and auto-reporting to tools and pve section
Introduce telemetry helpers in misc/api.func: _telemetry_report_exit (reports success/failure via post_tool_to_api/post_addon_to_api) and init_tool_telemetry (reads DIAGNOSTICS, starts install timer and installs an EXIT trap to auto-report). Integrate telemetry into many tools/addon and tools/pve scripts by sourcing the remote api.func and calling init_tool_telemetry (guarded with declare -f). Also apply a minor arithmetic formatting tweak in misc/build.func for RECOVERY_ATTEMPT.
Introduce create_service() to generate the immich-proxy systemd unit and run systemctl daemon-reload. Replace duplicated heredoc service blocks in install with a call to create_service, and invoke create_service during update before starting the service. Adjust unit WorkingDirectory to ${INSTALL_PATH}/app and ExecStart to run dist/index.js.
