UI overhaul: minimal top bar, license-first settings, footer-pinned check

Top bar (3-column layout)
-------------------------
- Col 1: PROSERVE Launcher wordmark.
- Col 2: license badge centered, the badge IS the click target now (a
  Border with an InputBindings MouseBinding LeftClick to OpenLicense).
  No more separate "🔑 Activer / changer" button cluttering the right.
- Col 3: ⚙ Paramètres + window chrome (min/max/close).
- "📁 Dossier" button removed from the top bar — install root is still
  reachable from Settings.

Footer (always visible)
-----------------------
- Row 1: "🔄 Vérifier les MAJ" pinned bottom-left, always shown. The
  optional "Annuler" button stays bottom-right while a download runs.
- Row 2: status text + progress bar, only shown when busy or after a
  status message — the previous "footer entirely hidden when idle"
  hid the check button too.

License flow split in two
-------------------------
Click on the license badge:
- License is active (valid / expired / revoked) → LicenseDetailsDialog
  opens. Header pill in matching status color (green/amber/red), shows
  owner, validity, issued date, machine ID with copy-to-clipboard. Two
  buttons: "🗑 Désactiver la license" (with confirmation) and Close.
- No license OR after deactivation → falls through to the existing
  OnboardingDialog for re-keying.

Settings rework
---------------
LICENSE section is now first in SettingsDialog with the same
green/amber/red colored chrome as the top bar — at a glance the user
sees the same status everywhere. Machine ID copy moved into this card.

Sign-manifest no longer needs exec()
------------------------------------
The "🔁 Sync" button in admin/versions.php previously shelled out to
`php tools/sign-manifest.php` via exec(). OVH mutualisé often disables
exec(), causing silent no-ops and the symptom the user just hit: the
ZIP changed (new size 469,657,770 vs manifest's stale 469,831,428) and
the launcher rejected it as size mismatch.

Refactor:
- New PSLauncher\Tools\SignManifest class with ->run() that does the
  hashing, latest-bump and Ed25519 signing in-process.
- tools/sign-manifest.php is now a 6-line wrapper for the class.
- admin/versions.php's 'sync' action calls the class directly via
  require_once + new — works on any host, no exec dependency.
