feat(windows-host): bundle + auto-run the web console in the installer

The Windows host installer shipped only the host exe + SudoVDA driver + FFmpeg, so a fresh install had no web management console — required for basically every user (status, paired devices, the PIN pairing flow). The console was only ever set up by hand on the dev box (build-web.ps1 + a hand-made PunktfunkWeb task whose web-run.cmd wasn't even committed). Bundle it into the same installer, mirroring the proven Linux punktfunk-web deploy. - windows-host.yml builds the Nitro node-server console (bun, deb.yml's shape) + fetches a pinned portable Node, smoke-boots it under node (/login == 200) to gate the build, and hands web/.output + node.exe to the pack script. - pack-host-installer.ps1 gains -WebDir/-NodeExe and stages the .output tree, node, and the two new scripts into the non-WOW64-redirected build area. - punktfunk-host.iss lays the payload into {app}\web\.output + {app}\node\node.exe, adds a wizard page for the console login password pre-filled with a crypto-random default (shown on the finish page; kept on upgrade), and runs web-setup.ps1. - web-setup.ps1 writes the ACL'd %ProgramData%\punktfunk\web-password (Administrators + SYSTEM), registers the PunktfunkWeb scheduled task (boot, SYSTEM, restart-on-failure -> web-run.cmd -> node on :3000), opens inbound TCP 3000, and starts it. web-run.cmd sources the host's mgmt-token + the password and runs the bundled node. - The console proxies the host's loopback mgmt API with the host's own %ProgramData%\punktfunk\mgmt-token (no host-code change). Uninstall removes the task + firewall rule. Validated locally: bun build -> node-server bundle, node boot serves /login (200) and gates /api (401). The Windows-only bits (ISCC compile, scheduled task, password page, firewall) validate on the Windows runner CI + on-glass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+  Provision the punktfunk web console after the host installer has laid down its payload
+  ({app}\web\.output, {app}\node\node.exe, {app}\web\web-run.cmd). Invoked elevated from the
+  installer's [Run] section; idempotent (safe to re-run on upgrade).
+
+    1. Sets the console login password file %ProgramData%\punktfunk\web-password
+       (PUNKTFUNK_UI_PASSWORD=...), ACL'd to Administrators + SYSTEM only:
+         - if -PasswordFile points at a non-empty temp file (a FRESH install collected one on the
+           wizard page), use that;
+         - else if the file already exists (UPGRADE), keep it untouched;
+         - else generate a random one (fallback, so the console never boots auth-misconfigured).
+    2. Registers the PunktfunkWeb scheduled task: at boot, as SYSTEM/Highest, restart-on-failure,
+       no execution time limit (a long-running server), running {app}\web\web-run.cmd.
+    3. Opens inbound TCP 3000 (the console port) on all profiles.
+    4. Waits briefly for the host's mgmt token, then starts the task.
+
+  The mgmt bearer token is NOT managed here — the host owns %ProgramData%\punktfunk\mgmt-token
+  (crates/punktfunk-host/src/mgmt_token.rs writes it on `serve`); web-run.cmd sources it.
