mo2: catch up to upstream 2.5.3 Betas 3-11

Multi-area sync against the upstream MO2 2.5.3 beta line. Roughly three
logical sections share the diff:

Catch-up (Betas 3-11):
- nxmaccessmanager: drop "supporter" from validRoles so non-premium
  supporters get the right download path (Beta 10)
- mainwindow: disable tutorial triggers at the trigger sites; Qt 6.11
  lockup on child windows (Beta 4)
- basic_games: add Kingdom Come Deliverance 2, Slay the Spire 2
  (Betas 11, 6)
- uibase: add NXM collections parsing fields/accessors + (?:nxm|modl)
  scheme support in NXMUrl (Beta 9)
- Starfield: blueprintPrefix() on IPluginGame; plugins.txt write
  suppression for blueprint plugins; hasInvalidBlueprint /
  hasUnpairedBlueprint diagnoses; Title-keyed content catalog
  consolidation (Betas 3-5)
- downloadmanager + systemtraymanager + organizercore + iuserinterface
  + settings: add Beta 11 "show notifications when downloads complete
  or fail" toggle and the showNotification plumbing
- nxmaccessmanager: restore upstream re-entry guard for OAuth refresh
  and the styled OAuth response page (Beta 11)
- organizer_en.ts and game-bethesda *_en.ts: pull upstream HEAD strings

Workarounds tab removed:
- Delete settingsdialogworkarounds.{h,cpp}; drop the tab in
  settingsdialog.ui; move "Enable archives parsing" into General
- Hardcode GameSettings::forceEnableCoreFiles() to true so the
  primary-master toggle-off bug (DLCs unchecked on tab refresh) can't
  recur; setter becomes a no-op
- No-op stubs for offlineMode, useProxy, useCustomBrowser, Steam
  appID/credentials, executablesBlacklist, skipFileSuffixes,
  skipDirectories — UI gone, accessors keep call sites green
- settingsdialognexus drops the custom-browser wiring; spawn drops the
  "Change the blacklist" Retry path

Beta 9 download manager port:
- fileID-first match in nxmFilesAvailable and
  nxmFileInfoFromMd5Available; filename remains the fallback
- NexusInterface::isActiveFileStatus() helper; rewrite of
  nxmUpdatesAvailable to use pickNewestVersion /
  findUpdateChainSuccessors / resolveInstalledFileId. ARCHIVED_HIDDEN
  now correctly treated as inactive
- std::optional<unsigned int> reservedID on DownloadInfo factories and
  on the three addDownload overloads; startDownloadURLs and
  startDownloadURLWithMeta return the canonical DownloadID instead of
  m_ActiveDownloads.size()-1 (which was the index, not an ID)
- QHash<unsigned int, DownloadInfo*> m_ByID maintained alongside
  m_ActiveDownloads at every mutation site; downloadInfoByID is now
  O(1) via m_ByID.value(id, nullptr)

LOOT remains intentionally stripped (lootcli build cruft cleaned up
separately). BSA wide-path skipped — Linux UTF-8 paths already work.
