refactor(jellyseerr): keep the server version out of the field UI; enforce it at login

The resolver field only needs to find the working URL — the Jellyseerr version requirement is irrelevant there and only polluted the UI.

- jellyseerrProbe: validate reachability + that it's a jellyseerr (no version gate, no version-too-low outcome).

- Drop the version-too-low reason from the whole resolver stack (types, resolve, hook, status text, i18n).

- Min version 2.0.0 stays enforced in JellyseerrApi.test() at login: now writes an error log + toast, and uses numeric isVersionBelow (fixes the "2.10.0" < "2.0.0" string-compare bug).
