Migrate 4 more Advanced items (Electron, Factory Reset, Virtual Consoles, Emergency Hotspot); bump to v2.11.0

New in install.sh's Advanced menu, alongside Diagnostics:
- menus/advanced_electron.sh: "Electron Maintenance" - the legacy
  "Manual Electron Update" and "Fix Blank Screen" combined into one
  submenu, sharing the binary-repair logic (electron_install_binary).
- menus/advanced_factory_reset.sh: "Factory Reset" - wipes config.json
  back to defaults only; addons are untouched.
- menus/advanced_virtual_consoles.sh: "Virtual Consoles" - toggles
  Ctrl+Alt+F1-F8 terminal login access.
- menus/advanced_emergency_hotspot.sh: "Emergency Hotspot" - auto-starts
  a WiFi hotspot if no internet is detected 60 seconds after boot. Its
  own runtime script and systemd unit now go through $BIN_DIR/
  $SYSTEMD_DIR like every other addon's own files, instead of the
  legacy's hardcoded /usr/local/bin and /etc/systemd/system.

That covers 8 of the legacy Advanced menu's 12 entries. Not migrated
this round: Export/Import Settings (pending a decision on rebuilding it
around actual paths vs. a hardcoded step list, or whether the future
web UI replaces the need for it) and Fix Squeezelite Audio (small
enough it may fold into the LMS addon instead of staying standalone).

Full command-level stubbed test suite per file, including set -e safety
checks (declined/failed paths never crash the session) and content
verification for every written file. Full 18-suite regression + real
end-to-end menu navigation via install.sh all pass.

+- Complete Uninstall (the last of the "destructive trio") is next, composed from each addon's own uninstall action plus core teardown rather than rewriting removal logic a second time. Upgrade and Full Reinstall stay in the legacy script for now — both are coupled to its own heredoc self-extraction of main.js/preload.js/etc, which has no modular equivalent yet.

+**Previous (v2.10.0):**
 - **Asterisk Intercom migrated, and redesigned in the process.** The legacy addon offered Client Only (Baresip SIP client), Server Only, and Full (server + client) — the latter two downloaded and ran a third-party installer from a separate "Easy Asterisk" repository to stand up a whole Asterisk PBX. That repository has since gone through a major rework upstream, so the PBX-install path is dropped entirely rather than carrying a dependency on code that's moved on without it. The migrated addon (`menus/addon_asterisk_intercom.sh`) now does only the client/endpoint piece: install Baresip and register this kiosk as one SIP extension against an Asterisk server you already have running elsewhere. It never installs or manages Asterisk itself. The legacy script's own three-option version is untouched, same as every other migrated menu.
 - Dropped the dependency on the (now-reworked) Easy Asterisk repo's GitHub API for version tracking — reads the real installed `baresip` package version via `dpkg` instead.
 - **New capability:** an uninstall option for the Baresip client — the legacy addon never had one.
