Launch batch: passwords, documents, wiki and tasks

Part of the launch batch covers everyday productivity. Each of these apps replaces a popular cloud service with something you fully control, and each has been tested in our homelab with real screenshots.

Vaultwarden is a lightweight, Bitwarden-compatible password vault that needs about 128 MB of RAM. Paperless-ngx scans, OCRs and archives your paperwork with full-text search, so finding an old invoice takes seconds.

Wiki.js is a modern wiki with a polished markdown editor, a good fit for documenting your own homelab. Vikunja is a to-do app with lists, Kanban, Gantt and CalDAV sync for people who want task management without a subscription.

Paperless-ngx, Wiki.js and Vikunja use PostgreSQL, while Vaultwarden gets by with SQLite. Check each entry for the exact requirements before deploying.
