GoMatrixHosting v0.6.7

GoMatrixHosting v0.6.7 🚀

- Major updates to the [recover-matrix-server](https://gitlab.com/GoMatrixHosting/gmhosting-external-tools/-/tree/main/recover-matrix-server) tool that automatically recover Matrix servers connected to AWx. See [#1](https://gitlab.com/GoMatrixHosting/gmhosting-external-tools/-/issues/1) tool. It's now faster and allows:
  - Recovering into a new member_id.
  - Recovering into a different subscription type.
  - Recovering to a new DigitalOcean region or on-premises location.
  - Preserving the previous subscriptions job templates history.
- Changed default usernames for accounts `@_janitor > @admin-janitor`, `@_dimension > @admin-dimension`, `@_mjolnir > @admin-mjolnir` due to `"Sending registration request...\nERROR! Received 400 Bad Request\nUser ID may not begin with _"` error.
- Added async timeout for media-repo size calculation.
