🐛 Fix restore-version-from-plugin promise hanging on restore failure (#9111)

Closes #9092.

`restore-version-from-plugin` accepted `_reject` as a dead parameter and
its stream had no `rx/catch`, so errors raised during the restore flow
(failed `rp/cmd! :restore-file-snapshot`, persistence timeouts, or
exceptions inside the watch body) silently swallowed instead of
rejecting the plugin-facing promise at `file.cljs:81`. Plugin code
that did `await version.restore()` would hang indefinitely on any
failure.

Wire `reject` through and wrap the emission with the same `rx/catch`
pattern already used by `create-version-from-plugins` in this file.

- Rename `_reject` to `reject` in the function signature
- Wrap the `rx/concat` body with `rx/catch` that calls `(reject error)`
  and returns `rx/empty` on error, mirroring `create-version-from-plugins`
- Add a CHANGES.md entry under the 2.17.0 Unreleased bugs-fixed section

 ### :bug: Bugs fixed
 
+- Fix plugin API `fileVersion.restore()` promise hanging indefinitely on restore failure [Github #9092](https://github.com/penpot/penpot/issues/9092)
 - Fix LDAP provider params schema typo (`bind-passwor` → `bind-password`) introduced during the `clojure.spec` → `malli` migration; the schema slot now matches the runtime key actually read by `prepare-params` (`:password (:bind-password cfg)`) and `try-connectivity` (`(:bind-password cfg)`), so a wrong type for the password no longer slips through unvalidated
 - Fix `login-with-ldap` silently dropping its error message on the `ldap-not-initialized` restriction (typo `:hide` → `:hint`); the message `"ldap auth provider is not initialized"` now actually surfaces in logs and error responses instead of being discarded into an unread key
 - Fix `PENPOT_OIDC_USER_INFO_SOURCE` flag being silently ignored (`userinfo` / `token`) in the OIDC callback, causing "incomplete user info" failures during registration [Github #9108](https://github.com/penpot/penpot/issues/9108)
