Introducing Orca Cloud: https://cloud.orcaslicer.com (#13414)

* Add OrcaCloud sync platform and preset bundle sharing system

  Introduce OrcaCloud, a cloud sync platform for user presets, alongside
  a preset bundle system that enables sharing printer/filament/process
  profiles as local exportable bundles or subscribed cloud bundles.

  OrcaCloud platform:
  - Auth to Orca Cloud
  - Encrypted token storage (file-based or system keychain)
  - User preset sync with
  - Profile migration from default/bambu folders on first login
  - Homepage integration with entrance to cloud.orcaslicer.com

  Preset bundles:
  - Local bundle import/export with bundle_structure.json metadata
  - Subscribed cloud bundles with version-based update checking
  - Thread-safe concurrent bundle access with read-write mutex
  - Canonical bundle preset naming (_local/<id>/... and _subscribed/<id>/...)
  - Bundle presets are read-only; grouped under subheaders in combo boxes
  - PresetBundleDialog with auto-sync toggle, refresh, update notifications
  - Hyperlinked bundle names to cloud bundle pages
