Subject: [PATCH] fix(dbus): preserve custom URI schemes in %U/%u Exec field
 expansion

QUrl::fromUserInput() treats unrecognized schemes as HTTP hostnames,
rewriting e.g. 'ksowpscloudsvr://start=RelayHttpServer' into
'http://ksowpscloudsvr//start=RelayHttpServer', which silently breaks
any application registered as a custom protocol handler via
x-scheme-handler MIME type (e.g. WPS Office OA integration).

Root cause: commit 9dd7e7f ('fix: dde-open file failed') replaced
QUrl{field} with QUrl::fromUserInput(field) to fix local file path
handling (toLocalFile() returning empty for bare paths). However,
fromUserInput's smart-guessing logic corrupts custom URI schemes by
treating the scheme name as an HTTP hostname.

Fix: detect fields that already carry a scheme ('://') and parse them
directly with QUrl::TolerantMode, which accepts non-RFC-compliant host
components such as 'start=RelayHttpServer'. Bare file paths (no '://')
continue to use fromUserInput as before, preserving the original fix.
