docs: clarify privacy-first Cloud model, drop managed hosting, add origins

- Add "Why LibrePortal" (privacy motivation) and "Acknowledgments"
  (built from scratch since 2023, inspired by bmcgonag/docker_installs)
- Reframe LibrePortal Cloud with the plain-English "courier with a sealed
  box" model: we only handle encrypted data, keys stay with the user
- Drop "Managed hosting — we run LibrePortal for you"
- Update Support to free community + optional paid priority

+## Why LibrePortal
+
+Too many services today treat your data as theirs to take — quietly
+overstepping boundaries that should never have been crossed. LibrePortal grew
+out of frustration with that: it's a way to run the apps you depend on on
+your own server, where your data stays yours. Privacy here isn't a feature to
+toggle — it's the whole point.

+## Acknowledgments
+
+LibrePortal has been built from scratch since 2023. Its spark of inspiration
+was a small installer script from Brian McGonagill (`OpenSourceIsAwesome`):
+[gitlab.com/bmcgonag/docker_installs](https://gitlab.com/bmcgonag/docker_installs).
+From that seed it grew start to finish — refined, extended, and refactored
+into the platform it is today.
