feat(server): Support date based ordering in Folder view

[rahul-kumar-saini]

Description

• Almost all photo views in Immich are sorted by creation date, strangely however, the folder view is sorted by filename
• Add support for sorting your content in the folder view by createdAt and not just the default filename
  • I almost feel as though the default here should be creation date if anything
• Implemented as an additional setting inside Storage Template settings
• Updated SDK based on open-api spec
• Partially implements features requested in this discussion post

How Has This Been Tested?

Thoroughly tested locally

• Verified folder sorting remains the same before/after the change (keep filename as default)
• Verified response of /api/system-config correctly contains new folderContentOrder
• Verified setting applies successfully
• Verified folder content sorting order does indeed reflect the updated setting

Screenshots

API Changes

The /api/system-config response now adds storageTemplate.folderContentOrder with value of "date" or "name":

    {
        ...
        "storageTemplate": {
            ...
++++        "folderContentOrder": "date"
        },
        ...
    }
