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.
* Rename import_local_ip to get_local_ip
Replaces all references to the helper function import_local_ip with get_local_ip across scripts and documentation for consistency. Updates usage examples and comments to reflect the new function name.
* Rename get_local_ip to get_lxc_ip and update usage
Replaces all references to get_local_ip with get_lxc_ip across scripts, documentation, and templates for clarity and consistency. Updates the implementation in core.func to improve IP detection for LXC containers, and adjusts helper functions in addon scripts accordingly.
