Add EPEL apps at latest versions and fix all EPEL dependency conflicts

Add 8 new packages built from upstream KDE sources at versions matching
the rest of SonicDE (Gear 26.04.3, Plasma 6.7.4):
- colord-kde 26.04.3
- dolphin-plugins 26.04.3
- filelight 26.04.3
- kde-gtk-config 6.7.4
- kde-inotify-survey 26.04.3
- ksanecore 26.04.3 (dependency for skanpage)
- plasma-discover 6.7.4 (with snap backend disabled)
- skanpage 26.04.3

These packages replace the EPEL versions and use SonicDE dependencies
instead of kf6-*/plasma-* packages, ensuring they are upgraded (not
removed) when SonicDE is installed alongside EPEL KDE.

Fix EPEL dependencies in existing SonicDE packages that caused packages
to be removed during dnf upgrade --allowerasing:
- sonic-desktop-interface: kde-cli-tools -> sonic-terminal-tools,
  kmenuedit -> sonic-launcher-menu-edit, kwrited -> sonic-write-daemon,
  signon-plugin-oauth2 and plasma-systemsettings changed to Recommends
- sonic-workspace: kio-fuse -> sonic-frameworks-io-fuse,
  polkit-kde -> sonic-polkit-agent,
  xdg-desktop-portal-kde -> xdg-desktop-portal-sonicde,
  plasma-keyboard and kde-settings-plasma changed to Recommends
- sonic-workspace-addons: kf6-plasma -> sonic-interface-libraries
- kde-gtk-config: breeze-gtk-common -> sonic-silver-gtk-common
- sonic-login-manager: kde-settings-plasma changed to Recommends
- kcm-soniclogin: plasma-systemsettings changed to Recommends
- sonic-rpm-macros: kde-qdoc-common changed to Recommends
- sonic-welcome-center: add Obsoletes for plasma-welcome

Also includes Obsoletes/Provides fixes across all spec files for proper
EPEL package replacement, and Conflicts tag removal from spec files.

Result: dnf upgrade --allowerasing from standard EPEL KDE removes 0
packages. dnf install of SonicDE packages installs 195 packages with
0 removals.
