Refactor entire project for Docker-native operation

Complete Docker-first refactor of the 6,800-line management script:

Core Architecture:
- Added is_docker() detection (/.dockerenv + /proc/1/cgroup check)
- Added asterisk_running() helper replacing all systemctl is-active calls
- Moved restart_asterisk_safe() to top-level with Docker/bare-metal branches
- Added webadmin_running(), start_webadmin(), stop_webadmin(), restart_webadmin()
  for process-based web admin management (replaces systemd service)

Functions Refactored (Docker-aware):
- fix_asterisk_systemd(): no-op in Docker (no systemd)
- install_asterisk_packages(): skips apt in Docker (pre-installed)
- install_baresip_packages(): skips in Docker (no local audio client)
- open_firewall_ports(): skips ufw in Docker (host responsibility)
- configure_asterisk(): skips systemctl enable in Docker
- enable_client_services(): skips entirely in Docker (no kiosk client)
- configure_baresip(): skips entirely in Docker
- configure_local_client(): shows error with guidance to use mobile clients
- run_client_diagnostics(): redirects to vpn-diagnostics
- fix_audio_manually(): not available in Docker (no audio hardware)
- uninstall_menu(): shows Docker-specific reset options
- manual_update_asterisk(): shows Docker rebuild instructions
- create_web_admin_service(): no-op in Docker (process-managed)
- web_admin_menu(): uses start/stop/restart_webadmin() instead of systemctl

Menu System:
- show_main_menu(): Docker-specific status display (Asterisk, Web Admin,
  VPN ICE status) with streamlined menu (no Client Settings option)
- submenu_install(): Docker shows Configure/Reset instead of Install/Uninstall
- submenu_tools(): Docker shows Room Directory, Update, VPN Diagnostics,
  DNS Whitelist (hides audio tools that need hardware)

Entrypoint:
- Proper signal trapping (SIGTERM/SIGINT) for clean shutdown
- Generates all Asterisk configs with STUN/ICE support from env vars
- Creates default device categories on first run
- Starts web admin as background process with env-based config

Dockerfile:
- Added lsof dependency (needed for port management)
- Added STUN port 3478 exposure
- Ensured /.dockerenv marker exists

Backward compatible: bare-metal installs work exactly as before.
