Remove LOOT integration entirely

The sort button was already hidden on Linux (setVisible(false)) and
the LOOT feedback path (LootDialog -> addLootReport) has always been
Windows-only, meaning the dirty/incompatibilities/missingMasters/messages
tooltip bullets and the dirty-plugin icon could never fire on Linux.
MO2 shipped lootcli + libloot for a load-order sort mechanism that was
unreachable from the UI.

Users who want LOOT can download it from https://github.com/loot/loot
and run it against their instance directly.

- Drop libs/lootcli/, libloot Dockerfile build step, and lootcli
  staging/patchelf in build-inner.sh
- Drop src/src/loot.{cpp,h}, src/src/lootdialog.{cpp,h,ui}
- Extract MarkdownDocument / MarkdownPage (used by UpdateDialog for its
  changelog view) into src/src/markdowndocument.{h,cpp}
- Strip addLootReport, makeLootTooltip, Loot::Plugin field, LOOT icon
  checks, and LOOT tooltip/isProblematic/hasInfo paths from pluginlist
- Delete sortButton widget, updateSortButton(), onSortButtonClicked(),
  and all m_didUpdateMasterList wiring
- Delete lootLogLevel setting, combo box, and "Integrated LOOT" group
  from the diagnostics settings tab
