Fix dnf upgrade --allowerasing errors with EPEL packages

Fix 4 errors that occurred when running dnf upgrade --allowerasing on a
system with EPEL KDE packages installed:

1. plasma-discover: Fix typo "sonic-desktop-interface)" -> "sonic-desktop-interface"
   in Requires (stray closing parenthesis in spec)

2. sonic-frameworks-sso: Remove Obsoletes for signon and signon-qt6.
   The SonicDE SSO package provides libsignon-qt6.so.0 while the EPEL
   signon-qt6 provides libsignon-qt6.so.1. Obsoleting signon-qt6 breaks
   accounts-qml-module-qt6 and signon-plugin-oauth2 which need .so.1.
   Both packages can coexist since they install different .so versions.

3. sonic-terminal-tools: Change kdesu dependency from strict version
   match (= 1:6.7.4-3) to >= 1:6.7.4 so it works with any kdesu 6.7.4
   release. Also add Obsoletes for kdesu < 1:6.7.4-2.el10 in the kdesu
   subpackage so it properly replaces the old EPEL kdesu from kde-cli-tools.

4. kamera: Add kamera package with Requires changed from kde-cli-tools
   to sonic-terminal-tools. The EPEL kamera requires kde-cli-tools which
   is obsoleted by sonic-terminal-tools, causing a circular dependency
   resolution failure.

5. skanpage: Change Requires from kquickimageeditor-qt6 (obsoleted by
   sonic-quick-image-editor-qt6) to sonic-quick-image-editor-qt6.

Result: dnf upgrade --allowerasing --best from standard EPEL KDE now
completes with 0 errors and 0 package removals.
