Some admin interface updates.

- Fixed bug when web-vault is disabled.
- Updated sql-server version check to be simpler thx to @weiznich ( https://github.com/dani-garcia/bitwarden_rs/pull/1548#discussion_r604767196 )
- Use `VACUUM INTO` to create a SQLite backup instead of using the external sqlite3 application.
  - This also removes the dependancy of having the sqlite3 packages installed on the final image unnecessary, and thus removed it.
- Updated backup filename to also have the current time.
- Add specific bitwarden_rs web-vault version check (to match letter patched versions)
  Will work when https://github.com/dani-garcia/bw_web_builds/pull/33 is build (But still works without it also).
