fix(ui): replace remote server binary from the mismatch dialog (#352)

* fix(install): prefer bundled server over release download for SSH remotes

SSH remote installs used , which only checks
 and ignores the server binary already shipped next
to the Windows executable. WSL already uses
to find that bundled binary.

Add  to auto-discover the bundled server and
fall back to the GitHub release download only when no matching local asset
exists. Switch  and  to use it.

This lets the Windows installer/zip (which already stages server binaries
under <exe>/server/) satisfy SSH remote installs without hitting the network.
The explicit  path keeps its strict no-fallback behavior, and WSL
remains bundled-only.

Refs: future issue/PR for bundling server binaries into Windows releases.

* style(install): fix rustfmt formatting in bundled-server tests

* fix(ui): replace remote server binary from the mismatch dialog

The version/protocol mismatch dialog previously offered a 'Restart Server'
button that only restarted the existing daemon without replacing the
incompatible binary. This left users stuck on the same mismatch after the
restart.

- Change restart_mismatched_remote_server to call replace_remote_server
  (replace binary + restart daemon) instead of restart_remote_server.
- Add a dedicated L10nKey::RemoteMismatchReplaceServer ('Update Server' /
  '更新服务器端') and use it for the dialog's action button and detail text.
- Update the mismatch title/detail copy so it describes replacing the server
  binary rather than restarting it.
