Browse the file manager ("Dateien") as a filesystem

Many teachers never use topics or boards; their material sits in the course's file area, and the tools answered "0 files" for courses holding dozens of worksheets — 21 of 26 courses on the live account. Persönliche, Kurs-, Team- and Geteilte Dateien live in the legacy file store, not in files-storage, and its service is not in the public ingress. The only way in is the legacy client: HTML listings, and GET /files/signedurl for a pre-signed download. core/legacy-files.ts turns that into one path tree — /my, /courses/<course>, /teams/<team>, /shared — resolving names that contain "/", ids anywhere in a path, and wrong or ambiguous names with a message saying what is there. A listing that does not parse throws; it never reads as an empty folder. Some of the legacy client's GET routes write (GET /files/share/ mints a share token), so getFileManagerPage allows only the listing routes, by pattern. Signed URLs are fetched with no credentials and must be https. - MCP: fs_list, fs_tree, fs_find and fs_read; get_course lists course files. - CLI: schulcloud fs ls, tree, find and get, recursive and resumable. - API: /api/fs/list, tree, find and file. - Index: the crawl walks the file manager (INDEX_FILE_MANAGER, on by default), so search covers the text inside those files and sync mirrors them under <course>/Kurs-Dateien. The local instance gains a fixture for all four areas. It needed a loopback, so signed URLs open from the host, and a pre-created bucket, since MinIO does not implement PutBucketCors. 135 tests. Smoke 55/55 live; 57/57 and 55/55 on the local instance. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
