Two bugs in cleanupOldBackups:
1. Filter was .endsWith('.zip') — swept manual backup-*.zip files too.
Now restricted to auto-backup-* prefix.
2. Age was derived from stat.birthtimeMs, which is 0 on overlayfs
(Docker default), making every backup appear epoch-old and get
deleted immediately. Age is now parsed from the filename timestamp
and falls back to mtimeMs (reliable on overlayfs).
Also converts inline require('./services/auditLog') calls to a static
import throughout scheduler.ts, and adds 8 unit tests covering the
fixed retention logic including the overlayfs regression case.
* add test suite, mostly covers integration testing, tests are only backend side
* workflow runs the correct script
* workflow runs the correct script
* workflow runs the correct script
* unit tests incoming
* Fix multer silent rejections and error handler info leak
- Revert cb(null, false) to cb(new Error(...)) in auth.ts, collab.ts,
and files.ts so invalid uploads return an error instead of silently
dropping the file
- Error handler in app.ts now always returns 500 / "Internal server
error" instead of forwarding err.message to the client
* Use statusCode consistently for multer errors and error handler
- Error handler in app.ts reads err.statusCode to forward the correct
HTTP status while keeping the response body generic
